基于蚁群觅食的生物学行为,以搜索最优食物源为目标,将约束纳入食物源优劣评价的启发式规则,采用成群募集和海量募集两种方式,并辅以局部搜索,以此引导蚁群寻找可行域中的最优解,构建为适用于连续约束优化问题的蚁群系统(constrainedantcolonysystem,CACS)。
Rejia area,Baiyu,Sichuan is characterized by the development of dyke rocks wich were emplaced in groups and in zones into the Sayan Formation (T(1-2))and the Genlong Formation(T3).
白玉县热加地区脉岩发育，成群成带集中分布于义敦群都萨岩组及上三叠统根隆组地层中，经研究认为脉岩为岛弧岩浆滞后侵入的钙碱性岩石，其形成与深部隆起、浅部伸展作用相关。
