Other Algorithms
Other algorithms integrated into modeFRONTIER borrow good ideas from Nature: natural systems can suggest the best strategies to solve specific problems.
SIMPLEX is a robust single-objective optimizer since it does not use the gradient of the objective function. The simplex is a geometrical figure moving in the design space, seeking for the optimum: the moving operators are reflection, expansion, and contraction. It mimics the behaviour of a predatory animal seeking for prey.
MOGT is based on Game Theory: a Multiobjective problem can be regarded as a competitive game, where each player is in charge of one single objective. The design variables are decomposed among the players. The result of the game is the Nash equilibrium point.
MACK is a design space sampling technique: the Multivariate Adaptive Crossvalidate Kriging algorithm is useful for placing designs where the interpolation is less accurate, in order to build a more precise response surface.
