Syslo }, YEAR = {1989}, NUMBER = {R-89-05}, INSTITUTION = ida, ADDRESS = idaaddr, ABSTRACTURL = {/publications/cgi-bin/tr-fetch.pl?r-89-05+abstr}, ABSTRACT = {We present the first polynomial-time algorithm for the subgraph isomorphism problem restricted to two-connected series-parallel graphs, which uses a new decomposition technique. We also show that this problem is in random NC, and that it is in NC if the input graphs are of bounded valence.}, IDANR = {LiTH-IDA-R-89-05}, NOTE = {Also in Proc. of the 15th International Qolloquium on Automata, Languages and Programming, Tampere, Finland, July 1988}
