In-memory data exchange
Description
- ugiocb.c: Exchanging data between model and host application. Callbacks for exchanging data: sparse data, string indices (requires burglar13.mos)
- ugiodense.c: Exchanging data between model and host application. Dense data (requires burglar6.mos)
- ugioscalar.c: Exchanging data between model and host application. Scalars (requires burglar12.mos)
- ugiosparse.c: Exchanging data between model and host application. Sparse data, string indices (requires burglar7.mos)

parameters
DATAFILE = '' ! Location of input data
SOLFILE = '' ! Location for solution data output
WTMAX = 102 ! Maximum weight allowed
end-parameters
declarations
ITEMS: set of string ! Index set for items
VALUE: array(ITEMS) of real ! Value of items
WEIGHT: array(ITEMS) of real ! Weight of items
soltake: array(ITEMS) of real ! Solution values
end-declarations
initializations from DATAFILE

end-declarations
! Objective: maximize total value
MaxVal:= sum(i in ITEMS) VALUE(i)*take(i)
! Weight restriction
sum(i in ITEMS) WEIGHT(i)*take(i) <= WTMAX
! All variables are 0/1
forall(i in ITEMS) take(i) is_binary
maximize(MaxVal) ! Solve the MIP-problem
! Output solution to calling application
forall(i in ITEMS) soltake(i):= getsol(take(i))
initializations to SOLFILE
soltake as "SOL"
end-initializations
