* Change Variable name of W_val and cost_val W_val and cost_val to W_history and cost_history To understand the purpose of variables easily * Revert "Change Variable name of W_val and cost_val" This reverts commit d75f37f. * Change Variable name of W_val and cost_val W_val and cost_val to W_record and cost_record To understand the purpose of variables easily * Change name of W_val and cost_val W_val and cost_val to W_record and cost_record To understand the purpose of variables easily hunkim#99 wasn't refactored by mistake * Change W_val cost_val W_val and cost_val to W_history and cost_history To understand the purpose of variables easily
