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)

Same as burglar2.mos, with input from/output to
calling application.

parameters
DATA = ''                        ! Location of input data
SOL = ''                         ! 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 'raw:'
[VALUE,WEIGHT] as DATA
end-initializations

declarations
take: array(ITEMS) of mpvar      ! 1 if we take item i; 0 otherwise
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 'raw:'
soltake as SOL
end-initializations
