Generalized Conflict-directed Search for Optimal Ordering Problems

no code implementations31 Mar 2021 Jingkai Chen, Yuening Zhang, Cheng Fang, Brian C. Williams

In this paper, we present Generalized Conflict-directed Ordering (GCDO), a branch-and-bound ordering method that generates an optimal total order of events by leveraging the generalized conflicts of both inconsistency and suboptimality from sub-solvers for cost estimation and solution space pruning.
