Combinatorial optimization problems with balanced regret

open access: yesDiscrete Applied Mathematics, 2023
For decision making under uncertainty, min-max regret has been established as a popular methodology to find robust solutions. In this approach, we compare the performance of our solution against the best possible performance had we known the true scenario in advance.

Fermionic quantum approximate optimization algorithm

open access: yesPhysical Review Research, 2023
Quantum computers are expected to accelerate solving combinatorial optimization problems, including algorithms such as Grover adaptive search and quantum approximate optimization algorithm (QAOA). However, many combinatorial optimization problems involve

Minimum Entropy Combinatorial Optimization Problems [PDF]

open access: yesTheory of Computing Systems, 2009
We survey recent results on combinatorial optimization problems in which the objective function is the entropy of a discrete distribution. These include the minimum entropy set cover, minimum entropy orientation, and minimum entropy coloring problems.

Optimization heuristics for the combinatorial auction problem [PDF]

open access: yesThe 2003 Congress on Evolutionary Computation, 2003. CEC '03., 2004
This work presents and compares three heuristics for the combinatorial auction problem. Besides a simple greedy (SG) mechanism, two metaheuristics, a simulated annealing (SA), and a genetic algorithm (GA) approach are developed which use the combinatorial auction process to find an allocation with maximal revenue for the auctioneer.

An improved approach to resolve a combinatorial optimization problem based CoronaVirus Optimization Algorithm [PDF]

open access: yesE3S Web of Conferences, 2022
Combinatorial optimization problems refer to intractable problems that can’t be performed using exact methods. The resolution of combinatorial problems geared towards the application of heuristics, metaheuristics also matheuristics, in order to provide ...

A new efficient transformation of the generalized vehicle routing problem into the classical vehicle routing problem [PDF]

open access: yesYugoslav Journal of Operations Research, 2011
Classical combinatorial optimization problems can be generalized in a natural way by considering a related problem relative to a given partition of the nodes of the graph into node sets.
