Summary0026044: Optimize math_GlobOptMin class to enter options for solutions of some specified problems
DescriptionAt present, math_GlobOptMin class always tries to find all global minimums of the given function (and spends more time for it). However, for some problems it is not necessary - only one global minimum is often enough (e.g. bug #25613).

Therefore, it is necessary to provide math_GlobOptMin interface, which allows finding one minimum only.
Steps To ReproduceNot needed.
TagsNo tags attached.
Test case numberNot needed

Remarks:

src\math\math_GlobOptMin.hxx
Rewrite the comment:
param what determine find single solution or all solutions.
as:
defines whether to find single solution or all solutions.

src\math\math_GlobOptMin.cxx
- Place the lines 225-228:
  if (myC > 1.0)
    myE3 = - maxLength * myTol / 4.0;
  else
    myE3 = - maxLength * myTol * myC / 4.0;
into the 'else' clause of the condition isFindSingleSolution.
- In lines 434-435, compute the value of "(aStepBestValue - myF) * myZ" only once before entering 'if' statement.
