ap-1636	Halupka, Ivan; Kollár, Ján; Pietriková, Emília	A Task-driven Grammar Refactoring Algorithm	2012	7	.pdf	application/pdf	4875	228	48	The difference in objective functions is the difference between the values of the objective function calculated for a post-grammar of the current population and the corresponding post-grammar of the previous population of grammars. The second step in the first phase of the algorithm creates corresponding post-grammars for each gram- mar population entity by applying its process chain to the initial grammar, and finally the third step calcu- lates the difference of the objective function calculated for the initial grammar and the post-grammar of the corresponding grammar population entity.	cache/ap-1636.pdf	txt/ap-1636.txt
