The heuristic method emploies a genetic algorithm in reducing the redundant attributes of all attributes. Besides taking fitness function as its heuristic function for its selection operation, the genetic algorithm uses the attribute\'s information entropy to construct the heuristic function for its mutate operation, and in this way it markedly elevate the convergence speed of attribute reduction.

"This is an important point," Dr. Sawyers told Medscape in an interview,"as it shows that the drug target continues to mutate and that BCR-ABL is the escape mechanism." Hence, further drug development should continue to focus on BCR-ABL and not on any of the other mechanisms that are thought to also be involved, he commented.
