大学的每个专业都要制定教学计划。假设任何专业都有固定的学习年限，每学年含两学期，每学期的时间长度和学分上限值均相等。每个专业开设的课程都是固定的，而且课程在开设时间的安排必须满足先修关系。每门课程有那些先修课程是确定的，可以有任意多门，也可以没有。每门课恰好占一个学期。试在这样的前提下设计一个教学计划编制程序-Each university should develop a professional teaching programs. The assumption that any profession has a fixed school years, each school year with two semesters, each semester and credits on the length of time limits are the same. Each professional courses are fixed, and the courses offered in the opening hours must meet the pre-relationship. Each course there are those who pre-course is determined, can have any number of doors, there will be no. Each accounted for just one semester courses. Test this premise in the design of a teaching plan programming
