xprs_optimize

Purpose
Invoke a solution process with the FICO Xpress Optimizer
This function will invoke the suitable optimzation routine for an XPRSprob object into holding an already loaded optimization problem. This function either invokes lpoptimize() or mipoptimize() depending on the properties of the input (continuous problem or with global entities/sets/indicator constraints/general constraints/piecewise linear constraints)
Synopsis
xprs_optimize(prob, sflags = "")
Arguments
prob 
an XPRSprob object, into which a problem has been loaded already.
sflags 
Flags to pass to the optimzation method, which specifies how to solve the initial continuous problem where the global entities are relaxed.
Return value
the XPRSprob object
Example

problemdata <- list()
problemdata$A <- matrix(c(1,0,0,1),nrow=2)
problemdata$rhs <- c(1,2)
problemdata$objcoef <- c(1,2)
problemdata$lb <- c(0,0)
problemdata$ub <- c(Inf,Inf)
problemdata$rowtype <- c("G", "E")
prob <- xprs_loadproblemdata(problemdata=problemdata)
xprs_optimize(prob)
