CFG extension for META framework

Grammatical inference (GI) of context free languages (CFG) is an actively researched area of computer science. There are some algorithm, based on different approaches, to induce CFGs and we are going to test and compare the standard CFG generation methods. The goal of the comparison is to develop a more efficient CFG induction method. In order to super the testing and comparison of algorithm, a GI and TM environment, called META, was created [1]. META provides only the basic functions for common grammar processing. In this paper, we present a CFG extension of it, and show some experimental result on CFG induction with META framework.
