Targetting the shortcomings existed in traditional algorithms, this paper mainly do two contributions, one is introduce a guiding function for greedy partitioning algorithm and another is improved traditional simulated annealing partitioning algorithm.

综合考虑了像素间相似性、邻域差和边缘走向三个因素来确定启发式引导函数,使蚂蚁沿着真正的边缘行走。
The visibility of the paths was determined by pixel similarity, neighboring difference and the direction of the edges synthetically, which made the ants move along the real edge pixels.
然后,第二个表被扫描,只扫描一次,那个函数引导我们到哈希表中适合的位置,并且从那里,你找到匹配的行指针。
Then the second table is scanned, only once, the function directs us to the proper slot in the hash table and from there you find the pointers to the matching rows.
JRuby的master branch已经大量利用到invokedynamic的好处了,通过invokedynamic操作引导大多数的Ruby函数调用。
JRuby's master branch already takes heavy advantage of invokedynamic, by routing most Ruby calls through invokedynamic operations.
So this is a teaser of functionality to come.
所以这是一个函数引导。
