# <ConsistencyModule:> circuit_g(+Succ,++CostMatrix,+ArcCosts,?Cost)

Constrains elements in Succ to form a Hamiltonian circuit with cost Cost, using native Gecode indexing.

Succ
  A collection of N different (domain) variables or integers
CostMatrix
  A NxN matrix collection of integers
ArcCosts
  A collection of N (domain) variables or integers.
Cost
  An (domain) variable or integer (array notation accepted).

## Description

This version of circuit/4 uses the native Gecode indexing, which starts from 0. This is different from normal ECLiPSe's indexing, which starts from 1.

This constraint can be embedded in a constraint expression in its functional form (without the last argument).

See circuit/4 for a more detailed description of this predicate.

## Examples

    CostM = []([](0,3,5,7),[](4,0,9,6),[](2,1,0,5),[](-7,8,-2,0)),
            circuit_g([1,2,3,0], CostM, [C0,C1,C2,C3], C).
