The Nineteenth Byte

i think allowing 0-indexing or 1-indexing in the code would be best, so that people can use what their language does, and the examples can be whichever one you prefer

Lembik

ok doing that

I quite like having the indexes and the actual substring outputted.... Do you actually hate that?

otherwise I will leave it

but if people hate it I will change it

xnor

8:28 AM

i don't like it, but it's your challenge

Lembik

@xnor true but I fear unpopularity :)

xnor

why do you like having both?

Katenkyo

@Lembik In the list defining a run, you could split the second dot in :
- Runs never overlap except for their border
- A Run is always maximal, `w[i,j]` isn't a run if there exist a run `w[i-x,j+y]` with `x` or `y` greater than `0`

xnor

@Katenkyo i like that

Katenkyo

@Lembik I think outputting both is fine, but it may be cumbersome for languages like retina

It really depends of what you want to do, in the end, you have to do a challenge that you would enjoy to do

Lembik

8:29 AM

@Katenkyo I gave in and changed it to intervals only

xnor

i'm interested in recursive strategies for these types of questions that don't index characters, which i find elegant, so I'd actually prefer substrings only

but i can see how that feels like it doesn't "find" the runs

Lembik

@xnor but that's really unclear as substrings will be repeated and you won't know which is which

@Katenkyo I didn't understand "split the second dot"

xnor

How about just "A run is maximal if it is not fully contained within any larger run"?

Lembik

@xnor that sounds good but it does mean you have to understand inclusion of intervals rather than strings

so it's not 100% complete as a description

xnor

hmm, i see

well, if you're having the intervals be output, it would be natural to phrase everything in terms of intervals

Katenkyo

8:33 AM

@Lembik As I read it, the second element of your list covers both the things I listed, Was suggesting to split it in 2 elements, making it easier to read.

xnor

and say that "An interval is X if the substring has properties Y"

Lembik

@Katenkyo got you

xnor

might you consider having just the number of runs be outputs?

it would free up code to represent runs as it wishes, which I find nice

and it's what the paper's result is about

Lembik

@xnor I would prefer not for this challenge. I have a follow up in mind which is fastest-code. That would just output the number of runs

@xnor but for this challenge I think it's interesting to actually output the runs

interesting and not 100% trivial :)

which is my main aim at ppcg

updated again

are you happy with the output format?

I have made it as loose as possible

I am tempted to post soon

xnor

yup, i'm happy with it

Lembik

8:37 AM

thanks!

xnor

per(w) <= |w|/2

that takes a bit to process

my intuition is "it has two full cycles"

Lembik

yes

xnor

maybe the idea of period and runs would be easier to digest by saying, there's a string that you try to extend cyclically, you do so as far as you can, and it requires at least two full repetitions

Lembik

that is the definition of periodic more

but you make a good point

xnor

i know mathematically, periodicity is that there's a p with f(x+p)=f(x) for all x, but I think for strings, people think of it more as concatenating a chunk

Lembik

8:40 AM

right but we need to be able to handle ababa

where ab is the minimal period

Q: Compute the runs of a string

Consider the following definitions taken from The number of runs in a string by W. Rytter. Note that word, string and substring are all roughly synonyms. A run in a string is a nonextendable (with the same minimal period) periodic segment in a string. A period p of a word w is any p...

xnor

yes, you'd have to think of cycling through the letters rather than concatenating the full string

Lembik

yes

I am sure you are right that some people will be confused

sadly :(

xnor

as defined, i think the empty string is always a run?

Lembik

hmm

xnor

8:42 AM

i mean any empty interval

Lembik

it's not an interval

xnor

by definition?

Lembik

right

I should fix that

but I am just checking.. is w[1,1] a run? It shouldn't be

xnor

indeed, it isn't, its period is 1, which would require it have length 2

Lembik

good point

so I just need to define j>=i

done

I always like to guess how long until the first answer :)

43 minutes?

Leaky Nun

8:48 AM

@Lembik How is aabaabaa periodic but aabaa not?

I say both are not periodic

Lembik

@LeakyNun aab aab aa the minimal period is 3 < 8

@LeakyNun aabaa, the minimal period is 3 > 5/2

Leaky Nun

where is the source supporting your definition?

Lembik

@LeakyNun you mean a definition of the minimal period of a string?

or the definition of a periodic word?

Leaky Nun

you know, saying that aabaabaa is periodic and aabaa is not

Lembik

@LeakyNun I just proved it to you using the definitions in the question!

just compute per(aabaa)=3 and per(aabaabaa) =3

@xnor I am looking forward to the fastest-code version of the question :)

Leaky Nun

8:54 AM

@Lembik I know, you defined them that way, but I'm asking is that common in the world

Lembik

@LeakyNun The definitions are from the paper I link to. I think they are standard

Leaky Nun

@Lembik alright

thanks

Lembik

np

xnor

@LeakyNun usually, things said to be periodic are infinite sequences of functions, so it just means there is a finite period, and there's no ambiguity

Leaky Nun

@xnor alright

xnor

8:55 AM

for finite objects, you need to somehow restrict the period, else everything is periodic with period bigger than its length -- i don't how how widespread the half-length restriction is

Lembik

@xnor it's standard in the world of combinatorial pattern matching (stringology) at least

@xnor otherwise all strings are periodic

Anonymous

@Lembik Function submissions are no harder to test. If you wish, you can ask people who submit functions to include a full program using that function for testing.

Lembik

@Mego you are right that if they also include a full program that is just as easy

@Mego I am generally inspired by tex.se which has a really nice culture of wanting to be as helpful as possible to people who know nothing

Anonymous

It's not an unreasonable request - I often do it. A lot of people who submit functions will also include a full program for testing.

Lembik

9:25 AM

all answers are supposed to be complete latex documents for example

@Mego but I don't really get the objection to complete program answers. I mean you can't compare Java and Jelly in any case

Anonymous

TeX.SE is a very different site. To name one major difference, they ask questions and get answers, where we pose challenges and get solutions.

Lembik

@Mego yes that is different. I think the idea that answers should be as widely accessible as possible is still good though

Anonymous

@Lembik To me, it's not about comparing different langauges - it's about not having to type public class A{public static void main(String[]a){...}} for every solution. That's pure boilerplate - it doesn't add anything to the actual solution.

Lembik

Let me be more precise, I don't mind what anyone else does :) I would just like my questions to ask for complete programs

variety is the spice of life and all that

Anonymous

Also, with some languages, the approaches with functions can be far more interesting than full-program solutions

Lembik

9:28 AM

@Mego If you are providing a full program as well then you still have to to type all that stuff

@Mego ah.. now why is that? "approaches with functions can be far more interesting than full-program solutions"

Katenkyo

@Mego And functions allow for some language to take an array as input :)

Anonymous

@Lembik That's arbitrarily overriding the defaults. A large portion of the community has decided that doing that is not good.

Lembik

@Mego it's not arbitrary! It's my preference

@Lembik you can, but it's frowned upon because people like to be free of how they will codegolf a solution

Mitch Schwartz

Anonymous

@Lembik Consider a challenge for determining if a string is a palindrome. The Python full-program solution would be s=input();print s==s[::-1]. A function submission might be f=lambda s:s==s[-1]and f(s[1:-1])

Lembik

@Katenkyo hmm.. but I am also going to ask them to produce a full program in any case!

@MitchSchwartz :)

Katenkyo

@Lembik Yes, but their function solution may be shorter

For instance, if I have to take an array as input in lua

Lembik

9:32 AM

@Katenkyo yes it may well be. I am not sure how relevant that is unless we are comparing across languages

Anonymous

@Lembik Restricting solutions to full programs because you don't want to test function submissions isn't "different sorts of questions" - it's imposing a restriction for a poor reason.

Lembik

@Mego it's not because I don't want to. It's because I think it makes the answers more interesting to the wider community

Katenkyo

function f(a) end is all I need as a boilerplate, for a full program, it would be loadstring("a=".. ...)()

Lembik

and hence makes PPCG a more attractive place

Mitch Schwartz

from another perspective, full programs are a natural default choice and allowing functions seems strange

Anonymous

9:33 AM

You know what makes solutions interesting? Not needing boring, static boilerplate that distracts from the actual solution.

Lembik

thanks :)

Katenkyo

@Lembik It's relevant if you want to find the optimal solution in ONE language

by disallowing functions, you may disallow the optimal codegolf for this problem

Lembik

@Mego I disagree. a)That is from the point of view of the answerer and b) if I am asking for a full program as well that doesn't make any differenec

@Katenkyo That's an interesting argument but I don't agree with it. There are optimal full programs and optimal functions. They are both optimal

@Mego I like this example

Katenkyo

@MitchSchwartz Why is that? You're ask to provide a piece of code that for x output y, it's the definition of a function ^^

Anonymous

How about finding the maximum element in an array? For Python 3, the full program would be: s=eval(input());print(max(s)). That's 4 function calls, of which 3 are only for getting input, processing it into a usable format, and outputting the result. As a function, it'd be max - the core of the solution.

Katenkyo

9:35 AM

@Lembik And there's a third category, optimal <lang> ^^

Lembik

@Mego I tend not to ask question which have such short answers

Mitch Schwartz

some languages don't have functions

Katenkyo

@MitchSchwartz But a program with input and output is a function

Lembik

@Katenkyo optimal <lang> is underspecified :)

Katenkyo

Also, note that disallowing function technically disallow Lua to be used

Mitch Schwartz

9:36 AM

um

Anonymous

@Lembik Like I said before, I think a compromise that is agreeable to all parties would be to allow function submissions, but request that those submissions be accompanied by a full program to illustrate how to use the submission and make testing easier.

Katenkyo

As even a full program in Lua is only a function

Lembik

@Mego This sounds like a nice compromise.

Mitch Schwartz

this internet thing is pretty great, isn't it

Lembik

@MitchSchwartz ? :)

Anonymous

9:37 AM

The difference between a function submission and a full program submission is that the program submission is standalone - it can be interpreted/compiled without needing any additional code. A function needs to be called, and possibly captured (in the case of unnamed lambda expressions), and possibly be wrapped in boilerplate code.

Mitch Schwartz

apparently people feel passionately about this issue

Lembik

@MitchSchwartz yes.. and there is some groupthink here too :)

@Sp3000 good point

Mitch Schwartz

i think "Also, with some languages, the approaches with functions can be far more interesting than full-program solutions" is a persuasive argument, and the talk about defaults and stuff is kinda just an appeal to authority, or something

Sp3000

Having said that though, I think some people pull the "community defaults" card too fast

I think for sum of two integers there was a comment about taking the integers from different input sources, and the OP saying no

Katenkyo

@MitchSchwartz in language poorly typed and were you have to prefix your variables with var or the like, a function means you already have a variable declared, and can be used as you like

Sp3000

Personally, I think it this case it's not unreasonable to require both nums from the same source

(Just as an example)

@Sp3000 I'm pretty sure the consensus is that input and output must each use exactly one method

A: Default for Code Golf: Input/Output methods

Programs may combine two or more input methods For example, if the inputs are a string and an int, a function that takes a string as an argument and an int from STDIN would be valid. The input format must still be consistent for a given program.

Fatalize

@xnor Main problem I see is people arguing about what they consider trivial or not

Since some people seem to think it's perfectly ok e.g. to use any non-empty string as a truthy value, I'd say people will probably argue similarly ridiculous things about the trivialness of answers

Honour would be interesting

11:55 AM

people have been pretty reasonable about things like not posting an answer when someone already posted basically the same answer, so these types of subjective things could possibly work without rules based on "feel" and "honor"

i guess it comes down to people already thinking that getting rep from built-in answers is somewhat dishonorable, which i do but other don't
