TreesearchLib

TreesearchLib is a C# framework for modeling optimization problems as search trees and a collection of algorithms to identify good solutions for those problems. It includes exhaustive algorithms, as well as heuristics.

Modeling optimization problems is performed by implementing a problem state class. This class maintains the decisions that have been taken, as well as the next choices, i.e., branches in the search tree. It is possible to compute bounds, which algorithms may use to discard parts of the tree.

Check out the SampleApp to see implementations of the following problems:

  • ChooseSmallestProblem - a fun problem which searches small values in the sequence of random number seeds
  • Knapsack - the famous {0, 1}-Knapsack, implemented using reversible search (allowing to undo moves), as well as non-reversible
  • TSP - the Berlin52 instance of the TSPLIB

These samples should give you an idea on how to use the framework for problem modeling.

The algorithms that are included are:

  • Branch and bound (depth-first search)
  • Breadth-first search
  • Limited Discrepancy Search
  • Beam Search
  • Monotonic Beam Search
  • Rake Search (and a Rake+Beam combination)
  • Pilot Method
  • Monte Carlo Tree Search

New hybrid algorithms can be implemented, also by making use of the existing algorithms.
