# set_up_probe(+Tasks, +Constraints, -Cost, ++Options, -Handle)

Sets up a linear probe for a set of constraints
*Tasks*
- A term containing some variables
*Constraints*
- A list of numerical constraints
*Cost*
- A cost variable
*Options*
- An options structure
*Handle*
- A variable which will record the handle of the matrix
used by the linear solver

## Description

The constraints are passed to **add_con**, which adds them to both the
fd and linear solvers. The cost is declared to be an integer. All the
finite domain variables in the term **Tasks** are associated with a demon
which forwards their bounds to the linear solver. (The priority of this
demon is one higher than that of the probe.)

**lp_demon_setup** is then invoked to set up the linear solver, with the
priority specified in the **Options** parameter. Solutions returned
by the linear solver are automatically used to update the tentative values
of all the variables.

### Resatisfiable

no
## Examples

?- Options = options{granularity:3,priority:5},
Cost=X1,
set_up_probe([X1,X2,X3],[X1>X2,X2>X3],Cost,Options,H).
