1. 1. Efficient Algorithms for Probabilistic Inference, Combinatorial Optimization and the Discovery of Causal Structure from Data

   Författare :Dag Wedelin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In the first article we present a network based algorithm for probabilistic inference in an undirected structure. We show that the algorithm can be used as a general purpose approximation algorithm for combinatorial optimization, and discuss issues of approximation and convergence. LÄS MER

3. 2. Models and solution methods for large-scale industrial mixed integer programming problems

   Författare :David Bredström; Mikael Rönnqvist; Dag Wedelin; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematic; linear programming MIP ; production-planning; MATHEMATICS; MATEMATIK;

   Sammanfattning : This thesis deals with large-scale industrial problems that can be formulated using mixed integer linear programming (MIP) models. Because of the large problem size, it is not often possible to apply standard solution methods. Therefore special techniques must be used. LÄS MER
