英文摘要
In this research, we study problems of finding a step-by-step transformation between two feasible solutions of a problem such that all intermediate results are also feasible. In particular, we study such problems for knapsack problem, which is one of the most fundamental problems in theoretical computer science, and for graph partitioning problem with supply and demand, which has some applications to power delivery network. We first analyzed the computational hardness of these problems, and then gave approximationalgorithms. Our approximation algorithms are best possible from the viewpoint of approximation ratio.
