简介：以便折衷探索/利用并且由房间geneticalgorithm启发了一个房间移动转线路操作员因为进化算法(EA)在这个paper.The定义领域被建议被划分成重新尺寸立方的子域(房间)和在一个n维的立方体的每individuallocates。如果他们在不同房间(探索)并且随后，thecrossover的房间数字配对的房间移动转线路第一交换从它的起始的地方转移firstindividual到另外的个人“s房间地方。如果他们已经在thesame房间，启发式的转线路(利用)被使用。有基因差异的vary的Cell-shift/heuristic转线路adaptivelyexecutes探索/利用搜索。当与最近的著名FEP进化算法作比较时，房间移动EAhasexcellent表演通常以十上的效率和功效使用了optimizationbenchmarks。
