There are many tasks that wait to be done. For this reason we have used a simpliﬁcation of the Allen, true if there is any instant when both its arguments are ex-. cial intelligence ideas for solving NP problems. Complexity theory considers not only whether a problem can be solved at all on a computer, but also how efficiently the problem can be solved.

Some of these rules can, be seen in Figure 1, covering the concepts that a part can, only play one note at a time, that note is either a pitch or a, deﬁning the major and minor scales and various modes.
