The set covering problem asks for the smallest collection of subsets whose union contains all elements in a given universe. As a canonical NP-hard challenge, it has inspired a rich array of exact, ...

Dealing with a problem here that probably has a clever solution which is not coming to me: I have an m x n grid. This grid contains some circles. I would like to find a set of squares that covers the ...

The vertex cover problem seeks a minimum-cardinality set of vertices in a graph such that every edge is incident to at least one selected vertex. As an NP-hard combinatorial optimisation challenge, it ...
