heuristic function

The fold distance of the heuristic function was used instead of its direct distance.

将启发函数中的直线距离替换为折距,对其进行了改进.

According to the structured partial topology map of the environment and global information, heuristic function is used to select a leaving point for expanding, and update the structured topology map, till a traversable path between starting point and goal is found in the topology map.

利用启发式函数选择适当的离开点进行扩展，并逐步完善拓扑图，避免了一次性构造整个环境拓扑图所带来的不必要的大计算量。

Supervised Learning of Heuristic Function for Refutation

反演启发函数的监督学习算法

This method begins with selecting logic element ( LE) with minimum connectivity factor as the seed of the packing, and then uses a heuristic function based on routability-driven to obtain the most appropriate LE to pack into the configurable logic block ( CLB).

选择连接因子最小的节点作为种子节点；采用基于布通率的启发式函数来选择最合适的逻辑单元（LE）装箱到可配置逻辑单元（CLB）内部。

Traditional analysis use accuracy as character of the heuristic function and the function's effect is to decrease the actual branching factor.

传统的分析以启发值的精确性作为启发函数的特征，启发函数的作用相当于减小有效的分支因数。
