请问优化过程中的TolCon是什么,如果超出默认值怎么办?
 
本人新手,在求解一个简单的单目标约束优化问题中,程序报错
fmincon stopped because the size of the current step is less than the default value of the step size tolerance but constraints were not satisfied to within the default value of the constraint tolerance.
大概细节我大概看了下,是因为TolX(TolX我知道是什么意思)已经达到终止的范围,但TolCon确超出默认值
relative max(constraint violation) = 5.50e-001 TolCon = 1e-006 (default)。
所以我想知道TolCon是什么意思,matlab上说The constraint tolerance called TolCon is the maximum of the values of all constraint functions at the current point.意思是在这个点上各约束函数的最大值?
