Global Extrema(全局最值) = 包括Local Extrema，在整体区间上的最大/最小值 这个最值可以是两边端点的位置 以y = x^2这个图像为例：在这个图像上，无论是局部或全局，也只有一个Local Minimum，就是在x = 0这位置，全局来说也只有x = 0这点最小，所以这点也是全局最小值 (局部极小值 = ...
global maximum是全局极大值的意思，local maximum是局部极大值的意思
global maximum/minimum,local maximum/minimum ,它们是全局极大值/极小值和局部极大值/极小值吧?怎样求全局?怎样求局部?假设这条题:f(x)=(x^1/3)*(2-x)^2/3 为什麼这条题没有全局极大跟极小值?只有局部的? 答案 我表示什么都不懂,不过给你个例子,题目:Global maximum and minimum?Find the global...

aThe MI-based approach may suffer from local maxima and an incorrect global maximum problem if intensity mapping relations in multimodal images are not spatially invariant or not globally statistical 基于MI的方法也许遭受地方最大值和一个不正确全球性最大问题,如果映射联系在multimodal图象的强度不是空间地...
Sometimes the goal of an optimization is to find the global minimum or maximum of a function—a point where the function value is smaller or larger at any other point in the search space. However, optimization algorithms sometimes return a local minimum—a point where the function value is sm...
