| 3 | Djinni is a framework for implementing heuristic search algorithms. The core elements are coded in C++ and python bindings are provided to simplify the user interface. The current version of Djinni implements compressed annealing (Ohlmann et al., 2004), a generalization of the well-known simulated annealing algorithm, and includes code used by Ohlmann and Thomas (2007) to solve the traveling salesman problem with time windows (TSPTW). The Djinni framework uses C++ templates to separate code into three parts: a heuristic search algorithm, a problem model, and problem data. Thus, it is straightforward to apply compressed or simulated annealing to problems other than the TSPTW. Furthermore, it is not difficult to apply different heuristic search algorithms to the same problem. |
