1、/简化版高校自动排课系统/排课任务简化后涉及：年级专业（教学班级，如计科13）、课程名称、任课教师、上课地点和时间/教学班级简化为不分人数，不分专业方向。/上课教室简化为不分理论课、实验课，不分教室容纳人数，不分与否多媒体。/上学时段简化为：一周五天，周一到周五，白天上课，上午四节，下午四节，/12(8:009:400)、34(10:0011:40)、56(14:0015:40)、78(16:0017:40)/为了便于解决，将五天的所有上学时段用数字019表达/上课地点和时间组合成一种整数数组（位集，bitset），每20个为1组为一种教室的上学时段安排/约束条件：1、教学班级的上学时间不能冲
