BinCounts使用 Mathematica，我需要优化一个根据;定义的函数。我想要最大化的参数定义了 bin 切点。
我认为问题在于 Mathematica 在给定数值之前根据参数扩展了目标函数，因此BinCounts抱怨 bin 规范不是“包含实数值、无穷大和 -Infinity 的列表”。
我认为以下是我正在尝试做的事情以及正在发生的事情的一个最小示例。我将非常感谢有关如何解决此问题的建议。
In[1]:= data = RandomReal[1, 30]; (* Make some test data. *)
In[2]:= f[a_, b_, c_] := BinCounts[data, {{0, a, b, c, 1}}] (* Shorthand to use below… *)
In[12]:= g[a_, b_, c_] := Max[f[a, b, c]] - Min[f[a, b, c]] (* Objective function. *)
In[13]:= NMaximize[{g[a, b, c], 0 < a < b < c < 1}, {a, b, c}] (* Try to oprimize. *)
During evaluation of In[13]:= BinCounts::cvals: The bin specification {{0,a,b,c,1}} is not a list containing real values, Infinity, and -Infinity. >>
During evaluation of In[13]:= BinCounts::cvals: The bin specification {{0,a,b,c,1}} is not a list containing real values, Infinity, and -Infinity. >>
During evaluation of In[13]:= BinCounts::cvals: The bin specification {{0,a,b,c,1}} is not a list containing real values, Infinity, and -Infinity. >>
During evaluation of In[13]:= General::stop: Further output of BinCounts::cvals will be suppressed during this calculation. >>
Out[13]= {0., {a -> 0., b -> 0., c -> 1.}}
