Algorithmic Aspects of Regularityer, there is a fast deterministic algorithm for finding such an approximation, and therefore many of the existential results based on the regularity lemma could be turned into constructive results. In this survey, we discuss some recent developments concerning the algorithmic aspects of the regularity lemma.作者: DEMUR 時間: 2025-3-22 23:07 作者: constellation 時間: 2025-3-23 03:43

The Anti-Oberwolfach Solution: Pancyclic 2-Factorizations of Complete Graphs for all such graphs, except a few small cases which we have proved are impossible. The solution method is simple but powerful. The pancyclic problem is intended to showcase the power this method offers to solve a wide range of 2-factorization problems.

On Dart-Free Perfectly Contractile Graphs Extended Abstractngth. A graph is perfectly contractile if every induced subgraph has a sequence of even-pair contractions that leads to a clique. We show that a recent conjecture on the forbidden structures for perfectly contractile graphs is satisfied in the case of dart-free graphs. Our proof yields a polynomial-作者: 潛伏期 時間: 2025-3-26 06:29
