Version 1.1 is an improvement of 1.0 in which we have fixed a few minor
bugs, improved the temporal quality of the plans, and added a few
opitions that can be set by the user (see the end of the README file).
While in version 1.0 mutex actions cannot (even partially) overlap, version
1.1 supports partial overlapping of mutex actions, as specified in
PDDL 2.1. This and the elimination of a minor bug in the implementation
of the heuristic function tend to improve the quality of the plans that
are gereneted. The new options, that by default are switched off, allow
to (1) set a CPU-time search limit (useful when the system cannot
find all solutions requested by the user); (b) reduce the size of
the space used by the mutex relations between actions, which are computed
at run time instead of being precomputed (useful for very large problems);
(c) take the partial overlapping of mutex actions into account during
the neighbourhood evaluation (sometimes leads to plans of better quality).
