I am working on a biological game theory summer project. I want to define a discrete probability distribution that updates every 1000 iterations of the game. I think I am using the discrete_distribution function improperly. I found some examples online, but some are difficult for me to comprehend...

Given below code access Excel files in each sub-folders of a folder (c:\charts).

Below is the problem taken from here. Question 10: GCD* The greatest common divisor of two positive integers a and b is the largest integer which evenly divides both numbers (with no remainder). Euclid, a Greek mathematician in 300 B.C., realized that the greatest common divisor of a and...

Looking for approach to do I have millions of files in a folder, files type will be with name PES _timestamp & DOM_timestamp. I have to aggrate all PES & DOM file name into one file which have same file name. The Aggregator program picks up only matching PES and DOM file pairs based on the tim...

The following method reads specially formatted text (TOML) from a file and parses the input using a parser to get a few properties, which are then used to create an object. The profiler tells me that this method is the bottleneck in my program. While parsing ~5000 files, this method eats up over...

I have made an implementation of Sieve of Eratosthenes algoritm in Java, and am not certain that it is as efficent as possible. I have looked at other peoples implementations on Google, and on this site, which raised concerns for me, as no one has taken a similar approach to me. public class si...

I'm writing a library that provides graphs for search algorithms. Usually you want to rank nodes using a priority queue. Normally you want to search for an specific node in the queue and lower its key (when you find a better path to it). Searching would be O(n) unless you know the index of the ...

Problem: Using recursion approach, find fibonacci sum without repetition of computation. sum_fibonacci(35) Solution: fibcache = {} def sum_fibonacci(n): if n == 0: fibcache[n] = 0 return fibcache[n] elif n == 1: fibcache[n] = 1 return fibcache[n] ...

Im confused why people use elemnts, what is the point to do that, I mean u can just use font-size Title vs title

I read the gaffer article on fix your tilmestep and also dewitters about fixed frame render rate. I agree with both parts, I think choosing a desired frame rate and locking it locking the frame rate at 24, 30, 60 or even 120 at the beginning of the project and then working within those limitatio...

The lines below are an extract from code used to generate a XML. Access freezes than crashes when executing the Set dlgSaveAs line. This seems to only happen when data is imported using .xls files, .csv's seem to work fine. Don't see what's wrong with the code and why it doesn't work with .xls/...

This question was been redirected, since it was addressed as a debugging question. I've found a Matlab implementations of WENO and ENO schemes by Jan S Hesthaven. I've translated them into Python and they produce the same results. Additionally, I found a WENO smoother, but this doesn't compute...
