The computer must have an Internet connection in order to use the optimized experimental designs from the Internet data base. The types of optimized designs: Latin hypercube (LH) type computer experiment plans optimized according to the Minimal Average Error, MaxiMin, Entropy, V. Eglājs’ potential energy criteria, classic factorial, Central composite, Box-Behnken type plans for implementing physical experiments. The metamodel (approximated input – response connection) creation methods: first, second, third order multivariable polynomials, locally weighted polynomial approximations, kriging. Optimization method: modified recurrent simulated annealing of the start for optimization of one criterion, the Pareto limit set generation for multicriterion optimization (if the specific version of the program contains multicriterion optimization).
