KEYWORDS

iterative methods, relative stopping criterion, convergence moni­
tor, solution sequence, reference solution

DESCRIPTION

Monitors  the  behaviour  of the iterates x managed by Iterative­
Solver. The convergence test is relative and is based on the dif­
ference  of  the  current iterate and a reference solution set by
attach, i.e., .

CONSTRUCTORS AND INITIALIZATION

Same as CMAbsRefSolution.

MEMBER FUNCTIONS

Same as CMAbsRefSolution, except attach for binding  a  reference
solution.
