In this paper we develop a parameterized algorithm for upward planarity testing that can be applied to all graphs and runs in .(.(.).. + .(.,ℓ).) time, where . is the number of vertices, . is theMast-Cell 发表于 2025-3-30 14:40:43
,Jenseits der Worte: „Abstrakte Oper Nr. 1“,e logarithmic utility functions. We derive a duality relation between buyers and sellers under such utility functions, and use it to design a polynomial time algorithm for calculating equilibrium price, for the special case when either the number of sellers or the number of buyers is bounded by a codeciduous 发表于 2025-3-30 16:49:52

For most of dominating set problems we prove asymptotically almost tight lower bounds. The results are applied to improve the lower bounds for other related problems such as the . problem and thegrandiose 发表于 2025-3-31 00:58:12
