void MBMesquite::LaplaceWrapper::set_cpu_time_limit ( double  seconds) [inline]

Specify timeout after which untangler will exit.

Specify a value less than or equal to zero for no limit

Definition at line 50 of file LaplaceWrapper.hpp.

References maxTime.

    {
        maxTime = seconds;
    }

Specify maximum number of iterations.

Specify a value less than or equal to zero for no limit

Definition at line 78 of file LaplaceWrapper.hpp.

References iterationLimit.

Referenced by main().

    {
        iterationLimit = limit;
    }

Specify factor by which to minimum distance a vertex must move in an iteration to avoid termination of the untangler.

Specify a value less than or equal to zero for no limit. Culling cannot be done w/out a limit on vertex movement
