Abstract (in Japanese) (See Japanese page) 
(in English) Self–stabilizing population protocols are impossible to design for some problems. For example, leader election on complete graphs cannot allow a self–stabilizing solution without knowing the exact number of nodes. To circumvent the impossibility, we previously introduced the concept of loose–stabilization, which relaxes the closure requirement of self–stabilization: a loosely–stabilizing protocol reaches a legitimate configuration in short time even when starting from any initial configuration and stays in legitimate configurations for sufficiently long time (but not forever). Sudo et al. proposed loosely–stabilizing leader election (LE) protocols first for complete graphs and then for arbitrary graphs using the upper bound N of graph size. In this paper, we propose a loosely–stabilizing protocol for the maximal independent set (MIS) on arbitrary graphs, which is another generalization of the first LE protocol concerning the graph topology, since the LE is equivalent to the MIS problem in complete graphs. Our protocol achieves better performance than that for the LE in arbitrary graphs, which is based on the following fact; the MIS is a local problem while the LE is a global problem.
