Structural Parameterizations for Equitable Coloringic . is fixed parameter tractable under well established parameters such as pathwidth and feedback vertex set, equitable coloring is W-hard. We prove that . is fixed parameter tractable when parameterized by distance to cluster or co-cluster graphs, improving on the FPT algorithm of Fiala et al.雕镂 发表于 2025-3-24 11:24:15

Query Minimization Under Stochastic Uncertaintyadaptive decision tree to find a correct solution to the problem in consideration while minimizing the expected total query cost. We show that sorting in this scenario can be performed in polynomial time, while finding the data item with minimum value seems to be hard. This contradicts intuition, si
