Extrema between curves has been made producing correct result for the cases of solution located near bounds. - Class math_GlobOptMin has been improved to use lower order methods of local optimization when high-order methods are failed. - Add support of conditional optimization (in bounds) in the classes math_BFGS and math_BracketMinimum. - Turn on conditional optimization in the case of usage of math_BFGS in the class math_GlobOptMin. - Correct mistake in distmini command, which caused incorrect reading of deflection parameter. - To avoid possible FPE signals, ensure initialization of fields in the class math/math_BracketMinimum. - In the algorithms math_BFGS, math_Powell and math_FRPR, take into account that the function math_MultipleVarFunction can return failure status (e.g. when computing D0 out of bounds). New test cases have been added. Tests cases are updated. // correct test case
