    3030Parameters of the generator are listed below. Modifying the default values for parameters other than the last five might result in invalid cuts.
    3131
    32   * {{{LUB}}}: Value considered large for the absolute value of a lower or upper bound on a variable. Default value: 1000. See method {{{setLUB()}}}.
    33   * {{{EPS}}}: Precision of double computations. Default value: 1e-7. See method setEPS().
    34   * {{{EPS_COEFF}}}: Precision for deciding if a coefficient of a generated cut is zero. Default value: 1e-8. See method {{{setEPS_COEFF()}}}.
    35   * {{{EPS_COEFF_LUB}}}: Precision for deciding if a coefficient of a generated cut is zero when the corresponding variable has a lower or upper bound larger than LUB in absolute value. Default value: 1e-13. See method {{{setEPS_COEFF_LUB()}}}.
    36   * {{{EPS_RELAX}}}: Value used to relax slightly the right hand side of each generated cut. Default value: 1e-8. See method {{{setEPS_RELAX()}}}.
    37   * {{{normIsZero}}}: Norm of a vector is considered zero if smaller than this value. Default value: 1e-5. See method {{{setNormIsZero()}}}.
    38   * {{{minReduc}}}: Reduction is performed only if the norm of the vector is reduced by this fraction. Default value: 0.05. See method {{{setMinReduc()}}}.
    39   * {{{limit}}}: Generate cuts with at most this number of nonzero entries. Default value: 50. See method {{{setLimit()}}}.
    40   * {{{away}}}: Look only at basic integer variables whose current value is at least this value from being integer. Default value: 0.05. See method {{{setAway()}}}.
    41   * {{{maxTab}}}: Controls the number of rows selected for the generation. Default value: 1e7. See method {{{setMaxTab()}}}.
     32  * {{{LUB}}}: Value considered large for the absolute value of a lower or upper bound on a variable. [[BR]]
     33    * Default value: 1000. See method {{{setLUB()}}}.
