基于蚁群优化算法的基本原理,分析线状目标简化过程中所需满足的约束条件,建立具体的算法设计模型,并引入长期禁忌表和局部搜索策略以提高算法的运算效率,给出解题的关键步骤。最后对该算法进行测试,简化结果表明将蚁群优化算法用于线状目标的简化,能较好地保持线状目标的几何形状特征,在顾及长度偏差和矢量偏差的同时有较高的压缩率。与道格拉斯算法简化结果对比表明,在相同的几何限差内蚁群优化算法所得目标函数值更佳。 更多还原

【Abstract】 According to the purpose for simplifying linear objects,the standards on map production and the basic principles of ant colony optimization algorithm,the simplification of linear objects is explained as a kind of combinatorial optimization problem,and the constraints that should be satisfied in the simplifying process are described by mathematical formulae at first.Then a model of automated simplification using ant colony optimization algorithm is put forward in detail and the key steps are give... 更多还原
