Raven Solvers

[brunorbqi]

Hello, I am installing the new version of RAVEN Toolbox, 2.8.0 and I am having the following problem, all model solvers are fail. Even the glpk, andI have a valid gurobi license. How can I fix this ? Best regards.

Could you please report the output from runtests('solverTests') ?

Ok, so that didn't give more useful information. Could you instead please try the following?

load(fullfile(findRAVENroot,'testing','unit_tests','test_data','ecoli_textbook.mat'));
setRavenSolver('glpk')
solveLP(model)

[brunorbqi]

load(fullfile(findRAVENroot, 'testing','unit_tests','test_data','ecoli_textbook.mat'));
setRavenSolver('glpk')
solverLP(model)
Undefined function or variable 'solverLP'.

Did you mean:

solveLP(model)
Error: File: optimizeProb.m Line: 195 Column: 17
"i" previously appeared to be used as a function or command, conflicting with its use here as the name of a
variable.
A possible cause of this error is that you forgot to initialize the variable, or you have initialized it implicitly
using load or eval.

Error in solveLP (line 103)
res = optimizeProb(prob,params);

The error message reported in your previous comment should now be fixed in RAVEN 2.8.1.

However, your reported error occurs when using 'soplex' as solver. Could you please double-check and confirm what error message you get if you first run setRavenSolver('glpk') or setRavenSolver('gurobi') ?

Actually, you report the same behaviour as in #478. There also all solvers were reported to fail. This was resolved by the fix that is included in RAVEN 2.8.1, so this will most likely also resolve the issue for you.

I updated the RAVEN to the latest version and worked very fine. Thank you very much for your atention !!! Best regards.
