I am using CPLEX-12.10 version in MATLAB 2019b:issue with options

  • 1.  I am using CPLEX-12.10 version in MATLAB 2019b:issue with options

    1. I set the following options for my the program in MATLAB:  options = cplexoptimset;
      options.lpmethod = 4;
      options.Param.solutiontype = 2;
      options.TolFun=1e-21; When I set algorithm 4 in the program, the output shows the Algorithm is 2
    2. Output for simulation: cplexstatus: 1
      cplexstatusstring: 'optimal'
      iterations: 23
      algorithm: 2
      time: 0
      message: 'Function converged to a solution x.'
    3. Why the program is not taking the algorithm given?
    4. Also, I have 48 decision variables and 114 constraints where I have multiple solutions to the problem. However, I see only one constraint is active from "lambda"i.,e.,lambda=1 for one constraint and lambda=0;for 113constraints
    5. How can I decide that the "lambda" shown by cplex is correct because I see 37 constraints are active when I checked it manually?
