Generate and Test Procedure.


This is the simplest search strategy. It consists of the following steps;

1. Generating a possible solution for some problems; this means generating
a particular point in the problem space. For others it may be generating
a path from a start state.

2. Test to see if this is actually a solution by comparing the chosen point at
the end point of the chosen path to the set of acceptable goal states.

3. If a solution has been found, quit otherwise return to step 1.

The generate - and - Test algorithm is a depth first search procedure because complete possible solutions are generated before test. This can be implemented states are likely to appear often in a tree; it can be implemented on a search graph rather than a tree.
