What is SYMPHONY?

SYMPHONY is an open-source solver for mixed-integer linear programs (MILPs) written in C. It can be used in three different main modes:

• As a callable library through either the native C interface or through the Osi.
• As an interactive solver using a command-line interface.
• As a framework to build customized solvers for specific problem classes.

SYMPHONY can be executed in either parallel (distributed or shared memory) or sequential modes and has a number of advanced features that make it unique, including the ability to

• solve biobjective MILPs,
• warm start the solution procedure, and
• perform basic sensitivity analyses.

以上這些介紹，是從 SYMPHONY Home Page 裡弄出來的。原本只是想裝來玩玩看，順便看看它針對 VRP，有什麼比較特殊的解法，要研究一下它的 code。

好死不死 … 我裝了老半天卻一直出現 “Unknown OS” 這個錯誤訊息，最後索性去 trace 一下 configure 的 code 好瞭解到底發生什麼事。不看還好，一看就一肚子火！

因為它除了支援常見的 OS 之外，連一些較不易見的其實都有支援，但它獨獨漏了 BSD 系列進去，只能說真的是戰你娘親！

還好我有備用的 Linux 主機可以用，不然還真不知道會浪費多少時間在它上面，真的夠了。不過我想有空還是讓它也有辦法支援 BSD 好了，真的沒空的話，那就寫信抱怨一下，天曉得下一個受害者在哪 囧rz
