optimal feasible solution

For satisfying the requirements of the time and space, it is reasonable and natural to compute certain sub-optimal feasible solution, and heuristic methods are designed based on such an idea.

为了满足求解此问题的时间、空间要求，寻找某个次优的、可有效计算的可行解成为自然而合理的办法。启发式方法就是基于这一思想所设计出的。

In the first feasible region above, the optimal solution is the right vertex of the solution space.

在上面的第一个可行域中，优化解决方案是解析空间中的右顶点。

In the first feasible region above, the optimal solution is the right vertex of the solution space, which is a triangle made by all the constraints.

在上面的第一个可行域中，优化解决方案是解析空间中的右顶点，而这个解析空间是一个由所有约束构成的三角形。
