In this paper a survey on existing algorithms for the capacitated minimum spanning tree problem (CMST) is given. The algorithms are classiied providing some insights into their fundamental principles. Reporting the literature, comparisons of the solution quality are given. As one result of the exploration it is observed that heuristic procedures for the(More)
The aim of the present study was to evaluate the expression of hedgehog (Hh) signaling molecules and the chemotactic activity of Sonic hedgehog (Shh) in monocytes from control (CTR) and diabetic patients with or without coronary artery disease (CAD). Previously several studies demonstrated that exogenous administration of Shh can induce angiogenesis and(More)

We consider the problem of designing ring networks for metropolitan area networks. Given a number of nodes representing locations that may be connected, the task is to construct a ring network by selecting a node subset and corresponding direct links. Any two nodes on the ring are enabled to communicate with each other so that the network provider gains a(More)
Continuous ow-shop scheduling problems circumscribe an important class of sequenc-ing problems in the eld of production planning. The problem considered here is to nd a permutation of jobs to be processed sequentially on a number of machines under the restriction that the processing of each job has to be continuous with respect to the objective of(More)
