What are the differences between NP, NP-Complete and NP-Hard? I am aware of many resources all over the web. I d like to read your explanations, and the reason is they might be different from what s ...

What does it mean to prove an upper bound or lower bound to an algorithm?

i have an algorithm that searches into a directory and search for all the text files in that directory and any sub-directory. Assuming i do not know how many sub-directories and sub-sub directories ...

I m interested to know if there is any literature out there on the relationship of complexity theory (emergence, complex systems, evolution) and software development processes. I read somewhere that ...

Brief: When academic (computer science) papers say "O(polylog(n))", what do they mean? I m not confused by the "Big-Oh" notation, which I m very familiar with, but rather by the ...

What is the fastest algorithm that exists up with to solve a particular NP-Complete problem? For example, a naive implementation of travelling salesman is O(n!), but with dynamic programming it can be ...

In Prolog, problems are solved using backtracking. It s a declarative paradigm rather than an imperative one (like in C, PHP or Python). In this kind of languages is it worth to think in terms of ...

Wikipedia says on A* complexity the following (link here): More problematic than its time complexity is A*’s memory usage. In the worst case, it must also remember an exponential number of ...
