Hi, I'm interfacing with AMPL for the first time, I tried example1 but it returns this error:

Incorrect usage. Correct command syntax is:
cplex
or
cplex -f <commandfile>
or
cplex -c "<command1>" "<command2>" ...
Exiting
Error at _cmdno 2 executing "solve" command
(file ex1.run, line 11, offset 136):
can't open

can you help me please?

IT WOUULD HAVE BEEN HELPFUL TO SEE HOW YOU GOT THOSE 2 FILES BEFORE RATHER THAN JUST SAYING YOU ALREADY CREATED.

Hello i write everything same as you do and save both files to my desktop but when i give the command"include deneme.run" it says Can't find file "deneme.run"
context: include >>> deneme.run <<< ;
What should i do or do i miss a point?

How to initialize a binary variable in AMPL?

And which solver to use for binary integer programming?

For a binary variable, is it necessary to include the constraint >= 0 when initializing?

[samarthzala]

It was very helpful one, just to know how can I attach the file format such as ".mod" and".run" to my own files?

Thanks, I enjoyed the video.

Dear Sir, I have cplex installed on my computer and installed the AMPS as shown in your previous video. When I run the example as shown in this video, I get error as -
Incorrect usage. Correct command syntax is:
cplex [-i] [-f <commandfile> | -c "<command1>" "<command2>" ...]
Exiting
Error at _cmdno 8 executing "solve" command
(file example1.run, line 11, offset 141):


Do we need to link cplex with AMPS? How? Please help me to solve this error.
Thank you for the informative videos.
