Property Value

The population size is calculated as the number of dimensions times the population multiplier. The default value is 15.

A higher population multiplier increases the population size, which can improve the algorithm's ability to explore the search space and avoid local optima. However, it also increases the computational cost and memory usage. Conversely, a lower population multiplier reduces the population size, which can speed up the optimization process but may lead to premature convergence and a higher chance of getting stuck in local optima.

The optimal population multiplier depends on the specific optimization problem. For problems with a large and complex search space, a higher population multiplier may be beneficial. For simpler problems, a lower population multiplier might suffice. It is often useful to experiment with different values to find the most effective one for a given problem.

The default value for the population multiplier is 15.
