Re: [ojAlgo-user] Removing Equalities and Inequalities methods

[Andy B. <ber...@gm...>]

Anders, My apologies, I had a few mistakes.

First, I didn't realize the Bold and Underlines show up as asterisks
in posts (or don't show up at all) so you couldn't see the 3 errors I
was referring to.
The first error I had was a Method not Found, for the equalities
method, such as in:

.equalities(AE_ms,BE_ms), or in your reply:


Second, it turns out the above error (plus the others) were entirely
my fault. I had multiple Workspaces open in Eclipse and when I
compiled the code the Ant Build went fine,
created the JAR files, and reported a successful build.  I didn't see
the compile errors listed in another (Markers) Window in Eclipse (i
looked at the wrong workspace I am guessing).
I also didn't realize that the Ant Build can report a successful build
in the Console window and create JAR files, but actually have compile
errors for the code.
Learned something new for the day :-).

So, I redid the download and compiled V32.5 successfully (based on the
build.properties file) with no errors (but with some warnings about
deprecated code, etc).
However, I still have one (new)issue, my code can no longer find the
import (in v32.5):

import org.ojalgo.optimisation.OptimisationSolver;

To 'check' my compile, I downloaded your compiled JAR file
ojalgo-32.0.jar and my code COULD then find the above import and runs
fine.
Has the OptimisationSolver class been permanently removed post v32.0?
I searched my workspace for 'OptimisationSolver' and came up with 3
occurrences, 2 commented out and 1 in a comment.

I will try the solution you mentioned below regardless, but could you
confirm that OptimisationSolver has been deprecated?

Thanks Much, Andy

just left a small snippet of the original post
can't find the OptimisationSolver anymore referenced below....



                QuadraticSolver.Builder tmpBuilder = new
QuadraticSolver.Builder(Q_ms, C_ms).*equalities*(AE_ms,
BE_ms).inequalities(AI_ms, BI_ms);
                QuadraticSolver tmpSolver = tmpBuilder.build();
                tmpSolver.*options.*timeLimit = Long.MAX_VALUE;
                OptimisationSolver.Result tmpResult = tmpSolver.*solve*();
                BasicMatrix tmpSolution = tmpResult.getSolution();
                PhysicalStore<Double> result =
tmpSolution.toPrimitiveStore();
