C# 中的免费优化库

Free Optimization Library in C#

提问by Graviton

Is there any optimization library in C#?

C#中是否有任何优化库？

I have to optimize a complicated equation in excel, for this equation there are a few coefficients. And I have to optimize them according to a fitness function that I define. So I wonder whether there is such a library that does what I need?

我必须在excel中优化一个复杂的方程，对于这个方程有几个系数。我必须根据我定义的适应度函数优化它们。所以我想知道是否有这样一个库可以满足我的需求？

Note that optimizers frequently benefit from the more extreme code (or assembly) optimizations that are not really possible in pure managed c#. IF serious speed is a concern then targeting an unmanaged implementation like NAG or MOSEK may well provide significant benefits that outweigh the hassle of making the data accessible to the unmanaged API (pinning the managed buffer or using memory mapped files for example)

请注意，优化器经常受益于更极端的代码（或程序集）优化，而这在纯托管 C# 中是不可能的。如果严重的速度是一个问题，那么针对 NAG 或 MOSEK 等非托管实现可能会提供显着的好处，超过使非托管 API 可访问数据的麻烦（例如，固定托管缓冲区或使用内存映射文件）

There do seem to be many different optimization libraries for C#. Thisone appears to be the most popular, however.

C# 似乎有许多不同的优化库。然而，这似乎是最受欢迎的。

They do offer a trial version, so you can verify that it will work for your particular situation before purchasing.

他们确实提供试用版，因此您可以在购买前验证它是否适用于您的特定情况。
