Analysis of multi-hop traffic grooming in WDM mesh networks
Traffic grooming is an essential functionality of WDM optical networks to provision multi-granularity subwavelength connections. Depending on the number of lightpaths allowed in a connection route, traffic grooming can be classified as single-hop traffic grooming (SH-TG) and multi-hop traffic grooming (MH-TG). MH-TG is...

Computer-aided inspection for substrate design
Substrate design is one of the major tasks involved in packaging design. In current business practice, the circuits of a substrate design are mostly designed by professional designers and produced by suppliers. Due to manufacturing limitations, some features of the circuit need to be modified before manufacturing. The ...

Generalization in the XCSF classifier system: Analysis, improvement, and extension
We analyze generalization in XCSF and introduce three improvements. We begin by showing that the types of generalizations evolved by XCSF can be influenced by the input range. To explain these results we present a theoretical analysis of the convergence of classifier weights in XCSF which highlights a broader issue. In...

New heuristic approaches for the dominating tree problem
Given an undirected, connected and edge-weighted graph, the dominating tree problem (DTP) seeks on this graph a tree with minimum total edge weight such that each vertex of the graph is either in this tree or adjacent to a vertex in this tree. The DTP is a NP NP -Hard problem. In the literature only two heuristics for ...
