Abstract: As a tool,state-space graph has a clear characteristic and applied very wide in the artificial intelligence.In this paper,the algebra characteristic about whether problems can be resolved or not is first analyzed,the concepts of poset state-space graph and kernel are put forward,the equivalence about whether problem can be resolved or not and Kernel is a bounded lattice is proved,two examples are given to illustrate this and  kernel-related nature are provided.

Key words: poset state-space graph, kernel, bounded lattice

摘要: 作为求解问题的工具,状态空间图具有直观、清晰的特点,在人工智能应用甚广。论文首次分析状态空间图有解的代数特征,提出序状态空间图及核的概念,证明了问题有解与其状态空间图的核为有界格是等价的,并给出两个实例加以说明,另外给出有关核的性质。
