Interpreting CPLEX output in MATLAB environment
显示 更早的评论
I'm using the CPLEX API on MATLAB environment to sove a LP, and I would like to know what is the meaning of the "algorithm" item on the output. Example:
cplexstatus: 1
cplexstatusstring: 'optimal'
iterations: 2909
algorithm: 1
time: 0.4380
message: 'Function converged to a solution x.'
Actually, my original problem is that I'm solving the LP with two differents approaches:
lpmethod = 4 --> Forces to use the barrier method (interior points method)
lpmethod = 0 --> The solver chooses automatically the method to be used.
I wanna know which method CPLEX used when I put the automatic choice, and I think my answer relies on this "algorithm" item.
Link to the "lpmethod" documentation --> https://www.ibm.com/docs/en/icos/20.1.0?topic=parameters-algorithm-continuous-linear-problems
Thanks in advance!
