Class TestLineSearchMore94

java.lang.Object

org.ddogleg.optimization.impl.TestLineSearchMore94

public class TestLineSearchMore94
extends java.lang.Object

The first test is a very basic test to see if it can minimize a simple problem. The remaining tests compare it against test problems with known results from More and Thuente's paper. These tests validate that this class produces the exact same output as the MINPACK-2 Fortran code. If the algorithm is improved then these tests are invalid.
