In this particular case, the optimalsolution for both the integer and non-integer problems is the same, but that's not always the case.
在这种特例中，整型和非整型的优化解决方案是相同的，但是并非所有情况都是如此。

Just know that the optimalsolution for a non-integer problem is always one of the polyhedron vertices.
我们只需要知道非整型问题的优化解决方案通常都是一个多面体的顶点就好了。

This paper discusses how to found its optimal model through the analysis of model check countermeasure and proposes its solution based on linear and non-linear programming.
