Postoptimal Analysis in Nonserial Dynamic Programming

Usually, discrete optimization problems (DOPs) from applications have a special structure, and the matrices of constraints for largescale problems have a lot of zero elements (sparse matrices). One of the promising ways to exploit sparsity in the interaction graph of the DOP is nonserial dynamic programming (NSDP), which allows to compute a solution in stages such that each of them uses results...

Benchmarking ordering techniques for nonserial dynamic programming

Five ordering algorithms for the nonserial dynamic programming algorithm for solving sparse discrete optimization problems are compared in this paper. The benchmarking reveals that the ordering of the variables has a significant impact on the run-time of these algorithms. In addition, it is shown that different orderings are most effective for different classes of problems. Finally, it is shown...

Nonserial dynamic programming and local decomposition algorithms in discrete programming

One of perspective ways to exploit sparsity in the dependency graph of an optimization problem is nonserial dynamic programming (NSDP) which allows to compute solution in stages, each of them uses results from previous stages. The class of discrete optimization problems with the block-tree matrix of constraints is considered. Nonserial dynamic programming (NSDP) algorithm for the solution of th...

Nonserial Dynamic Programming and Tree Decomposition in Discrete Optimization

Solving discrete optimization problems (DOP) can be a rather hard task. Many real DOPs contain a huge number of variables and/or constraints that make the models intractable for currently available solvers. There are few approaches for solving DOPs: tree search approaches (e.g., branch and bound), relaxation and decomposition methods. Large DOPs can be solved due to their special structure. Amo...

Declarative Dynamic Programming as an Alternative Realization of Courcelle's Theorem

Many computationally hard problems become tractable if the graph structure underlying the problem instance exhibits small treewidth. A recent approach to put this idea into practice is based on a declarative interface to specify dynamic programming over tree decompositions, delegating the computation to dedicated solvers. In this paper, we prove that this method can be applied to any problem wh...
