摘要

提出了一种用于确定任务集的任务排序数和优先约束的改进算法。优先图用于表示任务和约束。子图替换策略在确定一类NX-fold图的任务排序的确切数量时充当了一个预言器。对于非nx -fold图，oracle在低阶多项式时间内计算阶数的界限

Precedence constraints and tasks: how many task orderings?

An improved algorithm for determining the number of task orderings for a set of tasks and precedence constraints is presented. Precedence graphs are used to represent the tasks and constraints. A subgraph replacement strategy acts as an oracle in determining the exact number of task orderings for a class of NX-fold graphs. For non-NX-fold graphs the oracle computes, in low-order polynomial time, bounds on the number of orders
