我们提出了一种新的贪婪算法,用于最小化积分双次方多面体上的可分离凸函数。该算法从一个任意可行解开始,当前的可行解以贪婪的方式逐步走向最优解。\我们还证明,如果一个可行解不是最优解,那么在坐标陡降方向上至少存在一个最优解。
We present a new greedy algorithm for minimizing a separable convex function over an integral bisubmodular polyhedron. The algorithm starts with a.n arbitrary feasible solution and a current feasible solution incrementally moves toward an optimal one in a greedy way. \Ve also show that there exists at least one optimal solution in the coordinate-wise steepest descent direction from a feasible solution if it is not an optimal one.
