I am having the following issue with Open Solver. Please refer to the<br>
attached PowerPoint file. As shown on Slide 1, I created an extremely<br>
simple linear problem. If I choose the Bonmin solver and run the model, the<br>
result shown on Slide 2 occurs. As shown on Slide 3, if I try to select the<br>
CBC Linear Solver, then I get the error message shown on Slide 4. Clicking<br>
Debug leads to the result shown on Slide 5. The Case statement does not<br>
recognize "Cbc" because it appears to be looking for "CBC". I have been<br>
able to trace the code to the function GetNameValueIfExists (see Slide 6).<br>
The HasRef value appears to be coming up False. Eventually, the statement<br>
value = Mid(s, 3, Len(s) - 3) seems to set value to "Cbc". By adding the If<br>
statement to the bottom of the function, I can actually force it to return<br>
"CBC" which stops the error from occurring and allows the CBC Solver to work<br>
(Slides 7 and 8). It is not obvious to me why GetNameValueIfExists fails to<br>
return "CBC" without being hacked, but perhaps those of you who live and<br>
breathe the Open Solver software would have an idea?<br>
