perturb-minimize

Syntax:

perturb-minimize <key1> <value1> <key2> <value2> ...

Description:

where possible keys and value types are:

• algorithm : CG|MINRES (linear solver algorithm)
• CGBypass : bypass CG stopping criterion (residual increases 3 iterations in a row)
• nIterations : maximum number of iterations
• recomputeResidual : recompute residual every ten iterations (CG only)
• residualDiffThreshold: terminate if difference in consecutive residuals falls below threshold (MINRES only)
• residualTol : relative error of residual required to terminate solver (default value of 1e-4 is sufficient most of the time)

Any number of these key-value pairs may be specified in any order.

Properties:
