Two-phases Method and Branch and Bound Procedures to Solve the Bi–objective Knapsack Problem

TLDR
The classical 0–1 knapsack problem is considered with two objectives, and two methods of the “two–phases” type are developed to generate the set of efficient solutions.
Abstract
The classical 0–1 knapsack problem is considered with two objectives. Two methods of the “two–phases” type are developed to generate the set of efficient solutions. In the first phase, the set of supported efficient solutions is determined by optimizing a parameterized single-objective knapsack problem. Two versions are proposed for a second phase, determining the non-supported efficient solutions: both versions are Branch and Bound approaches, but one is “breadth first”, while the other is “depth first”. Extensive numerical experiments have been realized to compare the results of both methods.

Pareto simulated annealing—a metaheuristic technique for multiple‐objective combinatorial optimization

TL;DR: Pareto simulated annealing as discussed by the authors uses a sample of so-called generating solutions to explore its neighborhood in a way similar to that of classical simulated anealing. But it does not consider the problem of finding a good approximation of the set of efficient solutions of a combinatorial optimization problem.
