Package: TestFunctions 0.2.2.9000

TestFunctions: Test Functions for Simulation Experiments and Evaluating Optimization and Emulation Algorithms

Test functions are often used to test computer code. They are used in optimization to test algorithms and in metamodeling to evaluate model predictions. This package provides test functions that can be used for any purpose.
