摘要

考虑了一个关注工程应用的问题。假设对超大城市的连续访问已经实施。在进行了所有访问之后,需要返回起点(还考虑了对起点的更复杂的依赖性)。但最后一个要求并不严格:回归条件的一些弱化是可以接受的。在这些假设下,需要优化起点、路线和特定轨迹的选择。该解决方案使用了众所周知的动态编程(DP)。但是,当使用DP时,会出现与标准的终端组件对起点的依赖性相关的显著困难。起点枚举是必需的。我们考虑减少与通用(相对于起点)动态编程的应用变体相关联的枚举的可能性。当然,这种方法需要对问题进行一些转换。

ON ROUTING PROBLEM WITH STARTING POINT OPTIMIZATION
One problem focused on engineering applications is considered. It is assumed that sequential visits to megacities have been implemented. After all visits have been made, it is required to return to the starting point (a more complex dependence on the starting point is also considered). But the last requirement is not strict: some weakening of the return condition is acceptable. Under these assumptions, it is required to optimize the choice of starting point, route, and specific trajectory. The well-known dynamic programming (DP) is used for the solution. But when using DP, significant difficulties arise associated with the dependence of the terminal component of the criterion on the starting point. Starting point enumeration is required. We consider the possibility of reducing the enumeration associated with applied variants of universal (relative to the starting point) dynamic programming. Of course, this approach requires some transformation of the problem.
