The second approach ( now called forward pruning) has been dropped in favor of search extensions. 第二种方法(现在叫向前剪枝)则加进了扩展搜索。
The paper puts forward a improved Apriori arithmetic which achieves parallel processing via grouping, studies the construction of the grouping and the improvement of the efficiency for the predigestion of the join and pruning after grouped. 提出一种通过分组达到并行化的改进Apriori算法,研究了分组的构造以及分组后因连接步和剪枝步的简化而达到的效率的提高。
The authors put forward a kind of new pattern of high photoeffect training-"FI tree form", after many years of investigation into production and scientific experiments, aiming to solve the current problems that lie in training and pruning of greenhouse grape. 针对目前我国温室葡萄整形修剪中存在的突出问题,作者经过多年的生产调查和周密的科学试验,提出了一种高光效整枝模式&FI树形。
Secondly, this paper puts forward an improved genetic algorithm with retaining good individual and controlling infeasible solution, and then solves the established model combined with depth-first search algorithm with taking pruning in it. 然后,提出一种优秀个体保留和不可行解控制的遗传算法,并将其与带剪枝的深度优先搜索算法结合,完成模型求解。
