File t3.pl contains stubs for the implementation of predicates initMyData and perform.

File t3t contains tests ad predicates for testing.

Every definition of predicate t3test/4 contains a test, characterized by an identifier, the number of boxes to be delivered, the positions of the boxes as a list of pairs of coordinates, and an upper bound imposed on the length of the solution.

- for testing using a certain test, use predicate t3test/1, with the test identifier.
- for testing using all tests, with an end report, use t3testallinone/0.

Initially, consult the file t3t.pl in SWI-Prolog. This operation will consult the file t3.pl too.
