当和/或相对差距不再改善时，我如何intlinprog在“分支和绑定”阶段退出？fval我尝试了很多选择，但到目前为止都没有成功。对于下面的示例，我知道最佳值为6834。例如，如果连续五个步骤没有改善，我该如何实施提前停止？

 nodes     | total    | num int   | integer      | relative 
 explored  | time (s) | solution  | fval         | gap (%)

the convergence of this algorithm does not depend only on function value in each iteration, you can increase the function value tolerance in options or try scaling the problem.
