Abstract: The paper describes a novel algorithm, inspired by the phenomenon of wisdom of crowds, for solving instances of NP-hard problems. The proposed approach achieves superior performance compared to the genetic algorithm-based approach and requires modest computational resources. On average, a 6%-9% improvement in quality of solutions has been observed.

Keywords: knapsack problem; NP-complete; optimisation; travelling salesman problem; TSP; wisdom of artificial crowds; WoAC; wisdom of crowds; genetic algorithms.
