I don't know why there's no such function in std (at least I didn't find one). I need a conditional template function to return a reference to an object of T. T might be passed as a pointer or a smart pointer or by reference:
template <typename T>
void do_foo(T &t)
{
auto &&res = dereference(t...
Dabbling a bit more with arm assembly, I wrote a few functions to handle string splitting. The goal to was write a few reusable functions that could be combined to emulate (roughly) what C strtok() does. The approach was essentially to write strspn() and strcspn() approximations and then combine ...
I was watching Computerphile's video on using genetic algorithms to solve the Knapsack problem, and I decided to give it a whack.
For anyone running the code, the result_data pandas Data Frame contains the most recent iteration's breakdown of the genomes that are "still alive".

I recently was asked to upgrade some C++11 code to add a feature by which the user can set a time duration from the command line of the program. The requirement was to have a default time of 1500 ms but to allow it to be overridden by the command line parameters if the parameters are valid; inva...
I created this simple function:
def cleanup_data(*argv):
for df in argv:
df = df.dropna()
return argv
However, if I call cleanup_data(df1, df2), and later I do:
df1.isnull().values.any()
or
df2.isnull().values.any()
I get True.
What is wrong with my code?

I have a clunky (but working) piece of code as shown:
plus_cords = []
for i in range(len(pluses)):
plus_cords.append([ [pluses[i][0], pluses[i][1]] ])
for j in range(1, pluses[i][2] + 1):
plus_cords[i].append([pluses[i][0] - j, pluses[i][1]])
plus_cords[i].append([pluses[i...
Moving my chess engine over to a multi threaded implementation in order to properly handle time control. I'm using channels to send back whatever board state is found to be the best at each depth and having the main thread keep listening to that channel until the time is up.
Right now the search ...
