Plan to probe out a set of concrete tactics of expressing metaphor thinking of architecture design , detaily explained the architecture metaphor tactics combining instance 拟从中探索出一套表达建筑隐喻思维的具体手法,并结合实例对建筑创作中的隐喻手法进行了详细地阐述。
Most of the timed automata reachability analysis algorithms in the literature explore the state spaces by enumeration of symbolic states , which use time constraints to represent a set of concrete states 但是,随着系统规模的扩展,状态空间的大小呈现爆炸性的增长,往往超出了当前计算机的能力极限。这被称为“状态空间爆炸问题” 。
