# Convergence Tolerance

 Name: CONVERGENCE_TOLERANCE  Type: double Default Value: 1.e-3 Range: $$[0 - 1.79e308]$$

This sets a tolerance $$\epsilon$$ to determine whether the algorithm has converged to global optimality.

The solver will terminate if either of the following conditions are satisfied:

• $$BUB-LLB$$ $$\le$$ $$\epsilon$$ (an absolute optimality gap)
• $$BUB-LLB$$ $$\le$$ $$\epsilon$$ $$|LLB|$$ and $$BUB-LLB$$ $$\le$$ $$\epsilon$$ $$|BUB|$$ (a relative optimality gap)
