# STOPSTATUS

Description | Status of the optimization process.
Type | Integer
Topic area | Solution Process
Notes | Possible values are:
Value | Description
--- | ---
XPRS_STOP_NONE | no interruption - the solve completed normally
XPRS_STOP_TIMELIMIT | time limit hit
XPRS_STOP_WORKLIMIT | work limit hit
XPRS_STOP_CTRLC | user hit control C or sent a corresponding signal
XPRS_STOP_NODELIMIT | node limit hit in branch-and-bound
XPRS_STOP_ITERLIMIT | LP iteration limit hit
XPRS_STOP_MIPGAP | MIP gap is sufficiently small
XPRS_STOP_SOLLIMIT | solution limit hit
XPRS_STOP_MEMORYERROR | insufficient memory led to error in memory allocation
XPRS_STOP_USER | user interrupt
XPRS_STOP_SOLVECOMPLETE | MIP solve completed without fully exploring the tree
XPRS_STOP_LICENSELOST | license has been lost, all flexible licenses are in use
XPRS_STOP_NUMERICALERROR | solver encountered numerical errors
XPRS_STOP_MIPSTAGE | stopped due to MIPSTOPSTAGE
XPRS_STOP_SOLVECOMPLETE can occur when a disconnected component is found to be infeasible, proving the whole problem to be infeasible without finishing the branch and bound search. XPRS_STOP_NUMERICALERROR can occur during a multi-objective solve, when the first objective solves to optimality, but when solving a subsequent objective the problem is found to be infeasible due to numerical issues associated caused by fixing the earlier objectives.
Set by routines | XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
