selectShifting()

SCIP_RETCODE selectShifting ( SCIP * scip, SCIP_SOL * sol, SCIP_ROW * row, SCIP_Real rowactivity, int direction, SCIP_Real * nincreases, SCIP_Real * ndecreases, SCIP_Real increaseweight, SCIP_VAR ** shiftvar, SCIP_Real * oldsolval, SCIP_Real * newsolval )

static

returns an integer variable, that pushes activity of the row in the given direction with minimal negative impact on other rows; if variables have equal impact, chooses the one with best objective value improvement in corresponding direction; prefer fractional integers over other variables in order to become integral during the process; shifting in a direction is forbidden, if this forces the objective value over the upper bound, or if the variable was already shifted in the opposite direction

Parameters

scip	SCIP data structure
sol	primal solution
row	LP row
rowactivity	activity of LP row
direction	should the activity be increased (+1) or decreased (-1)?
nincreases	array with weighted number of increasings per variables
ndecreases	array with weighted number of decreasings per variables
increaseweight	current weight of increase/decrease updates
shiftvar	pointer to store the shifting variable, returns NULL if impossible
oldsolval	pointer to store old solution value of shifting variable
newsolval	pointer to store new (shifted) solution value of shifting variable

static

returns a fractional variable, that has most impact on rows in opposite direction, i.e. that is most crucial to fix in the other direction; if variables have equal impact, chooses the one with best objective value improvement in corresponding direction; shifting in a direction is forbidden, if this forces the objective value over the upper bound

Parameters

scip	SCIP data structure
sol	primal solution
minobj	minimal objective value possible after shifting remaining fractional vars
lpcands	fractional variables in LP
nlpcands	number of fractional variables in LP
shiftvar	pointer to store the shifting variable, returns NULL if impossible
oldsolval	old (fractional) solution value of shifting variable
newsolval	new (shifted) solution value of shifting variable
