Warm starts for LP changing with each iteration (in R)

    It's not currently possible to warm-start the barrier method. To warm-start simplex, you can:

    • Set the PStart attribute for every variable and the DStart attribute for every constraint, or
    • Set the VBasis attribute for every variable and the CBasis attribute for every constraint.

    When warm-starting simplex, you may want to experiment with setting LPWarmStart to 2 to pass the warm-start information to the presolved model.
