Search
This chapter describes various search engines. The engines fall into the following categories.
Easy to use engines for single, all, and best solution search.
Engines that offer additional support for:
Recomputation allows to trade space for time, allowing to solve problems which otherwise would use too much memory.
The execution of engines can be killed.
Solutions computed can be returned as procedures or first-class computation spaces.
The search object supports demand-driven search for single, all, and best solutions. Search can be stopped and resumed as needed. The object supports recomputation and the different kinds of output as described above.
Parallel search engines use multiple networked computers to speed up the exploration of search trees. During exploration of a search tree entire subtrees are delegated to Oz engines that run on different computers in parallel.
Oz Explorer
Besides of the engines described here, Mozart features the OzExplorer, an interactive graphical search engine. A short description of its use can be found in Section 3.3 of ``Finite Domain Constraint Programming in Oz. A Tutorial.''. Reference information on the Oz Explorer can be found in ``Oz Explorer - Visual Constraint Programming Support'', a research paper is [Sch97].
