The comparison of algorithms complexities can be reduced to the comparison of complexity functions. In two previous papers, we obtained some results related to the comparison of one-variable complexity functions using complexity classes. In this paper, we extend some of these results to...

The composition of semantic web services is a very important and actual problem in the semantic web services research area. There are several semi-automatic approaches for this problem, but most of the results are related to automatic approaches. In this paper we present an automatic approach...
