Solving Set Cover with Pairs Problem using Quantum Annealing
Here we consider using quantum annealing to solve Set Cover with Pairs (SCP), an NP-hard combinatorial optimization problem that plays an important role in networking, computational biology, and biochemistry. We show an explicit construction of Ising Hamiltonians whose ground states encode the solution of SCP instances. We numerically simulate the time-dependent Schrödinger equation in order to...
متن کاملThe Set Cover with Pairs Problem
We consider a generalization of the set cover problem, in which elements are covered by pairs of objects, and we are required to find a minimum cost subset of objects that induces a collection of pairs covering all elements. Formally, let U be a ground set of elements and let S be a set of objects, where each object i has a non-negative cost wi. For every {i, j} ⊆ S, let C(i, j) be the collecti...
متن کاملSolving Bus Terminal Location Problem Using Simulated Annealing Method
Bus network design is an important problem in public transportation. A main step to this design is determining the number of required terminals and their locations. This is a special type of facility location problem, which is a time-consuming, large scale, combinatorial problem. In a previous attempt by the authors, this problem had been solved by GAMS, based on a branch and bound algorithm.&...

متن کاملExact and heuristic approaches for the set cover with pairs problem
This work deals with the Set Cover with Pairs Problem (SCPP) which is a generalization of the Set Cover Problem (SCP). In the SCPP the elements have to be covered by specific pairs of objects, instead of a single object. We propose a new mathematical formulation using extended variables that is capable of consistently solve instances with up to 500 elements and 500 objects. We also developed an...
