Introduction I have these three iterative deepening search algorithms. The main "research" attempt was to find out a bidirectional version of iterative deepening search, and it turned out to be superior compared to three other algorithms. The code I would like to get reviewed is as follows: pac...

I'm a first year student and this is the first exercise that will count into my grade. I had to code a connect four variant, where instead of forming a line of 4 identical pawns, a player needs to build a palindrome (palindrom in Polish) of 5 pawns on a 8x8 board. You play by choosing a column...

I am learning python for work and am trying to generate a matrix containing an experimental set up. The design requires a number of individuals (n) to see a number of options (k) in a random(ish) order. The number of times each option follows the others needs to be the same - so 1 will be seen af...

My goal is to take a source list of vectors and apply a mapping to each vector. The mapping creates a list of lists. When the vector size in each list element is large (~20000), and the number of elements in the source list is large (~5000), my program does not seem to be efficient. How can I opt...

I am aware of Dijkstra's paper on why goto is harmful; but I thought it would still be fun to make a bubble sort using goto. So I did. I thought I'd share the code here. Cheers! void bubbleSort(int arr[], int size){ int counter = 0; BottomUp: //This starts from the lowest array index and goe...

Often when reading data from a sequence (IEnumerable<T>) in multi-threaded code, a consistent snapshot needs to be taken inside a lock before using it in a longer operation. I'd like to simplify that by creating an API that does it within the enumerator implementation. So in the manner of LINQ e...
