Cyclic vs. non-cyclic constraint evaluation

Global Cyclic Cumulative Constraint

This paper proposes a global cumulative constraint for cyclic scheduling problems. In cyclic scheduling a project graph is periodically re-executed on a set of limited capacity resources. The objective is to find an assignment of start times to activities such that the feasible repetition period λ is minimized. Cyclic scheduling is an effective method to maximally exploit available resources by...

The Cyclic SEQUENCE Constraint

In rostering problems, we need to find a schedule that satisfies various constraints. Ergonomic constraints, that place restrictions on a number of consecutive days, are common (Bourdais, Galinier, & Pesant 2003) . To model such rules, several global constraints have been introduced. For example, the STRETCH constraint (Hellsten, Pesant, & Beek 2004) is useful for limiting the length of stretch...

Effect of Surgical Removal of Endometriomas on Cyclic and Non-cyclic Pelvic Pain

Background Endometriosis is a complex disease with a spectrum of pain symptoms from mild dysmenorrhea to debilitating pelvic pain. There is no concrete evidence in the literature whether endometriotic cyst per se, causes pain spectrum related to the disease. The aim of the present study was to evaluate the effect of surgical removal of endometriomas on pain symptoms. MaterialsAndMethods In this...

Finite $p$-groups and centralizers of non-cyclic abelian subgroups

A $p$-group $G$ is called a $mathcal{CAC}$-$p$-group if $C_G(H)/H$ is ‎cyclic for every non-cyclic abelian subgroup $H$ in $G$ with $Hnleq‎ ‎Z(G)$‎. ‎In this paper‎, ‎we give a complete classification of‎ ‎finite $mathcal{CAC}$-$p$-groups‎.
