(Constrained) Numerical Optimization Problem (NOP)

Category : Code

A general constrained numerical optimization problem (NOP) may be written as follows: where is the objective function and each is a constraint function to be satisfied, and and are constants. Each function can be nonlinear and non-smooth. If there is no constraint (i.e., ), then the problem becomes an unconstrained optimization problem. NOP Instance Implementation

Ant colony optimization (ACO), or ant system (AS), is a class of metaheuristic optimization algorithms inspired by the emergent search behavior using pheromone trails in natural ants. We present CGO-AS, a generalized ant system (AS) implemented in the framework of cooperative group optimization (CGO), to show the leveraged optimization with a mixed individual and social

The cooperative group optimization (CGO) system consists of a group of intelligent agents cooperating with their peers in a sharing environment for realizing a common intention of finding high-quality solution(s) based on the landscape representation of an optimization task. Numerical Optimization CGO has also been applied on numerical optimization problem (NOP) to find solutions in high-dimensional nonlinear continuous space.
