We study extremal problems concerning the M6bius function kt of certain families of subsets from 0,, the lattice of faces of the n-dimensional octahedron. For lower order ideals ff from O,, tP(~}] attains a unique maximum by taking ff to be the lower two-thirds of the ranks of the poset. Stanley sho
In this paper, we present an approach for ®nding a minimum cost partition of the nodes of a directed acyclic graph into subsets of a given size, subject to the constraint that the precedence relationships among the elements are satis®ed, based on the concept of simulated annealing. Simulated anneali
