Set covering problem wikipedia
WebWe'll define the value of a subset as how many new elements of U it covers. The pseudocode is roughly: Sets covered = [] cover_to_output = [] while covered != U: highest_val = max (S, key = lambda subset: value (subset)) add sets in highest_val to sets covered append highest val to cover_to_output return cover_to_output

In combinatorics and computer science, covering problems are computational problems that ask whether a certain combinatorial structure 'covers' another, or how large the structure has to be to do that. Covering problems are minimization problems and usually integer linear programs, whose dual problems are called packing problems.

In computer science, the problem of finding a minimum vertex coveris a classical optimization problem. It is NP-hard, so it cannot be solved by a polynomial-timealgorithm if P ≠ NP. show entireWebThe problem consists of selecting a set of workers to perform all the tasks, while minimizing the cost. This is known as a set-covering problem. The key idea in modeling a set-covering problem as an integer program is to associate a 0/1 variable with each worker to represent whether the worker is hired. show entriesWebareas.
