Interior Point Algorithm Options: Stopping Criteria

STOP_C=s: is used to determine whether optimization should stop. At the beginning of each iteration, if complementarity (the value of the Complem-ity column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, optimization will stop. This option is discussed in the "Stopping Criteria" section.
STOP_DG=s: is used to determine whether optimization should stop. At the beginning of each iteration, if the duality gap (the value of the Duality_gap column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, optimization will stop. This option is discussed in the "Stopping Criteria" section.
STOP_IB=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total bound infeasibility $\sum_{i=1}^n infeas_{b i}$ (see the infeas_b array in the "Interior Point: Upper Bounds" section; this value appears in the Tot_infeasb column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, optimization will stop. This option is discussed in the "Stopping Criteria" section.
STOP_IC=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total constraint infeasibility $\sum_{i=1}^m infeas_{c i}$ (see the infeas_c array in the "Interior Point Algorithmic Details" section; this value appears in the Tot_infeasc column in the table produced when you specify PRINTLEVEL2=2) is <= s, optimization will stop. This option is discussed in the "Stopping Criteria" section.
STOP_ID=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total dual infeasibility $\sum_{i=1}^n infeas_{d i}$ (see the infeas_d array in the "Interior Point Algorithmic Details" section; this value appears in the Tot_infeasd column in the table produced when you specify PRINTLEVEL2=2) is <= s, optimization will stop. This option is discussed in the "Stopping Criteria" section.
AND_STOP_C=s: is used to determine whether optimization should stop. At the beginning of each iteration, if complementarity (the value of the Complem-ity column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, and the other conditions related to other AND_STOP parameters are also satisfied, optimization will stop. This option is discussed in the "Stopping Criteria" section.
AND_STOP_DG=s: is used to determine whether optimization should stop. At the beginning of each iteration, if the duality gap (the value of the Duality_gap column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, and the other conditions related to other AND_STOP parameters are also satisfied, optimization will stop. This option is discussed in the "Stopping Criteria" section.
AND_STOP_IB=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total bound infeasibility $\sum_{i=1}^n infeas_{b i}$ (see the infeas_b array in the "Interior Point: Upper Bounds" section; this value appears in the Tot_infeasb column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is <= s, and the other conditions related to other AND_STOP parameters are also satisfied, optimization will stop. This option is discussed in the "Stopping Criteria" section.
AND_STOP_IC=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total constraint infeasibility $\sum_{i=1}^m infeas_{c i}$ (see the infeas_c array in the "Interior Point Algorithmic Details" section; this value appears in the Tot_infeasc column in the table produced when you specify PRINTLEVEL2=2) is <= s, and the other conditions related to other AND_STOP parameters are also satisfied, optimization will stop. This option is discussed in the "Stopping Criteria" section.
AND_STOP_ID=s: is used to determine whether optimization should stop. At the beginning of each iteration, if total dual infeasibility $\sum_{i=1}^n infeas_{d i}$ (see the infeas_d array in the "Interior Point Algorithmic Details" section; this value appears in the Tot_infeasd column in the table produced when you specify PRINTLEVEL2=2) is <= s, and the other conditions related to other AND_STOP parameters are also satisfied, optimization will stop. This option is discussed in the "Stopping Criteria" section.
KEEPGOING_C=s: is used to determine whether optimization should stop. If a stopping condition is met, if complementarity (the value of the Complem-ity column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is > s, optimization will continue. This option is discussed in the "Stopping Criteria" section.
KEEPGOING_DG=s: is used to determine whether optimization should stop. If a stopping condition is met, if the duality gap (the value of the Duality_gap column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is > s, optimization will continue. This option is discussed in the "Stopping Criteria" section.
KEEPGOING_IB=s: is used to determine whether optimization should stop. If a stopping condition is met, if total bound infeasibility $\sum_{i=1}^n infeas_{b i}$ (see the infeas_b array in the "Interior Point: Upper Bounds" section; this value appears in the Tot_infeasb column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is > s, optimization will continue. This option is discussed in the "Stopping Criteria" section.
KEEPGOING_IC=s: is used to determine whether optimization should stop. If a stopping condition is met, if total constraint infeasibility $\sum_{i=1}^m infeas_{c i}$ (see the infeas_c array in the "Interior Point Algorithmic Details" section; this value appears in the Tot_infeasc column in the table produced when you specify PRINTLEVEL2=2) is > s, optimization will continue. This option is discussed in the "Stopping Criteria" section.

This option is discussed in the "Stopping Criteria" section.
AND_KEEPGOING_C=s: is used to determine whether optimization should stop. If a stopping condition is met, if complementarity (the value of the Complem-ity column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is > s, and the other conditions related to other AND_KEEPGOING parameters are also satisfied, optimization will continue. This option is discussed in the "Stopping Criteria" section.
AND_KEEPGOING_DG=s: is used to determine whether optimization should stop. If a stopping condition is met, if the duality gap (the value of the Duality_gap column in the table produced when you specify PRINTLEVEL2=1 or PRINTLEVEL2=2) is > s, and the other conditions related to other AND_KEEPGOING parameters are also satisfied, optimization will continue.
