Detailed Description

Extended group representing a constrained nonlinear problem.

This class represents a constrained system of nonlinear equations:

$\begin{split} f(x,p) &= 0 \\ g(x,p) &= 0 \end{split}$

where $x\in\Re^n$ is the solution vector, $p\in\Re^m$ is a set of constraint parameters, $f(x,p)\in\Re^n$ is represented by some LOCA::MultiContinuation::AbstractGroup, and $g(x,p)\in\Re^m$ is a constraint represented by a LOCA::MultiContinuation::ConstraintInterface object. Newton steps for this system are computed via some LOCA::BorderedSolver::AbstractStrategy which is specified via the constraintParams argument to the constructor.
