    Hi,

    Could you post your model's coefficient statistics?

    Hi,

    Model has 408 quadratic constraints
    Coefficient statistics:
    Matrix range [2e-05, 3e+00]
    QMatrix range [5e-09, 2e+00]
    QLMatrix range [1e-05, 1e+00]
    Objective range [1e+00, 1e+00]
    Bounds range [2e-02, 5e-01]
    RHS range [1e-02, 8e-01]
    QRHS range [1e-05, 6e-01]
    Presolve removed 0 rows and 2 columns

    Continuous model is non-convex -- solving as a MIP.

    Warning: diagonal adjustment of 2.2e-08 performed to make Q PSD
    Warning: diagonal adjustment of 1.9e-08 performed to make Q PSD
    Presolve removed 4 rows and 6 columns
    Presolve time: 0.51s
    Presolved: 25610 rows, 6697 columns, 305515 nonzeros
    Presolved model has 4 quadratic constraint(s)
    Presolved model has 6390 bilinear constraint(s)
    Variable types: 6697 continuous, 0 integer (0 binary)
