8), Yamamoto and Nakao(1995) , etc.). For efficient implementation of the verification algorithms on computers, it is necessary that these constants can be estimated as close as possible to their optimal values. In Nakao, Yamamoto and Kimura(1998), the optimal constant was derived for quadratic elements as well as a nearly …
