Abstract

Strategies for locating multiple relative optima in a multimodal optimization problem using multiple-point simulated annealing are proposed. Two strategies incorporated with multiple-point simulated annealing are developed to increase the capabilities of locating more relative optima in a nonconvex design space. Balance strategy involves the use of a balance function that evaluates the degree of design spreading over the entire design space and create a corresponding direction bias in the subsequent design-change process. Bounce strategy evaluates the degree of design crowding and aims to push designs away from the crowd center by creating a direction bias in the next design-change process. Both strategies are evaluated on a number of illustrative multimodal problems. Intr
