Figure 2From: On the complexity of Minimum Path Cover with Subpath Constraints for multi-assemblyIn Fig. 2(a), subpath constraint P , in Fig. 2(b) the reduction of [20] which replaces path P by node v P connected to the end points of P , removes all internal nodes of P , and adds all transitive edges from and to v1 and v2. In Fig. 2(c), a case not covered by the reduction in [20].Back to article page
