ASP中与域无关的费用最优规划

Domain-Independent Cost-Optimal Planning in ASP

University of Alberta(阿尔伯塔大学)

David Spies, Jia-Huai You, Ryan Hayward

摘要:

研究了ASP中的成本优化规划问题。目前的ASP计划可以平凡地扩展到成本最优的一个,通过添加弱约束,但只有一个给定的最大完工时间(步骤数)。我们希望有一个计划,保证全局最优。在本文中,我们提出了两种方法来解决这个问题。首先,我们将展示如何设计一个成本最优的计划组成的两个ASP程序并行运行。利用从中吸取的教训,我们开发了一种全新的方法来进行成本最优规划,无级规划,这是完全免费的最大完工时间。实验比较这两种方法与唯一已知的成本最优规划在SAT显示良好的潜力无级规划ASP。该文件正在考虑被TPLP接受。

英文摘要:

We investigate the problem of cost-optimal planning in ASP. Current ASP planners can be trivially extended to a cost-optimal one by adding weak constraints, but only for a given makespan (number of steps). It is desirable to have a planner that guarantees global optimality. In this paper, we present two approaches to addressing this problem. First, we show how to engineer a cost-optimal planner composed of two ASP programs running in parallel. Using lessons learned from this, we then develop an entirely new approach to cost-optimal planning, stepless planning, which is completely free of makespan. Experiments to compare the two approaches with the only known cost-optimal planner in SAT reveal good potentials for stepless planning in ASP. The paper is under consideration for acceptance in TPLP.
