YALMIP cannot invoke the GLPK solver on my MIP, as per the error message below. YALMIP is able to invoke lpsolve, intlinprog, cbc, and scip on my MIP.

if memory serves me right, yalmip does not use the opti glpk interface, but some native ones

The YALMIP documentation states that GLPK is interfaced through Opti Toolbox: https://yalmip.github.io/solver/glpk/

True, appears to be incorrect. Regardless, you should not use glpk as it is pretty weak
