LLB Tolerance


Name:
LLB_TOLERANCE
Type: double
Default Value: 1.e-3
Range: \([0 – 1.79e308]\)

This tolerance is used to compare solutions of upper bounding problems and lower bounding problems. These two numbers are typically results of two separate local optimisation problems, potentially using two different third-party solvers.





Therefore, they are prone to high numerical error. Tightening this tolerance can accelerate convergence, but it can increase the risk of eliminating the global solution due to error accumulation.
