cplex - Ampl Cplex 解决错误

Question

为什么每次我尝试使用 CPLEX 求解模型时都会收到以下消息:

ampl: option solver Cplex;
ampl: model Anchor_QP.mod;
ampl: solve;

Incorrect usage. Correct command syntax is:
   Cplex
or
   Cplex -f <commandfile>
or
   Cplex -c "<command1>" "<command2>" ... 
Exiting
Error executing "solve" command:
can't open C:\Users\ozgutr\AppData\Local\Temp\at16996.sol

Answer 1

线程here建议您应该使用:

option solver cplexamp;

而不是:

option solver cplex;

它还说:

Looks like you are running a command-line version of CPLEX rather than CPLEX for AMPL. "cplexamp" is the name of the CPLEX-for-AMPL executable distributed by IBM.

我个人没有尝试过，但这是有道理的。
