append

OPL function to produce new arrays of integers, integer variables, or interval variables through concatenation

Purpose

This OPL function enables you to produce new arrays of integers, integer variables, or interval variables through concatenation.

context	type
Model files (.mod) - Not allowed in a CPLEX constraint block.	int[] interval[]

Syntax

append( int, int, ... )
append( int[], int, ... )
append( int[], int[], ... )

append( dvar int, dvar int, ... )
append( dvar int[], dvar int, ... )
append( dvar int[], dvar int[], ... )

append( dvar interval, dvar interval, ... )
append( dvar interval[], dvar interval, ... )
append( dvar interval[], dvar interval[], ... )

Description

This OPL function enables you to produce new arrays of integers, integer variables, or interval variables through concatenation. You can use this function within IBM ILOG Script statements by specifying the OPL namespace:


( Opl.xxx() )

Example

using CP;

range R=1..10;
dvar int x[R] in 0..20;
dvar int y[R] in 0..20;

minimize sum(i in R)(x[i]+y[i]);
subject to
{
  allDifferent(append(all(i in 1..2) x[i],all(i in 4..6) y[i]));
}

  noOverlap(append(all (h in houses, w in workerNames, t in taskNames) normalPlan[h][w][t], 
                   all (h in lines, w in workerNames, nt in newTasks) newPlan[h][w][nt]));
