Application of graphics matching algorithm in formula discovery from data
Yong Guan · Jisuanji gongcheng yu sheji · 2009
The traditional theory of the formula discovery from data used heuristic search,with the functions library expanded,there is still a combination of function explosion phenomena.Based on the composite function curve still has a primary function graphics fea-tures,the paper started from the function curve's characters,used the matching method of graphics,made the various primary function's curves as an element of the search library.Matching the objective functions and the curves in the library used the matching method of Hausdorff distance,experiments show that this method can search the prototype functions quickly and efficiently,the efficiency of the whole system algorithm is improved.
