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

   Constrains elements in Succ to form a Hamiltonian circuit with cost Cost. This version uses native Gecode indexing.

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

Type
   library(gfd)

Description
  This version of circuit/3 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/3 for a more detailed description of this predicate.

Examples
   [eclipse 10]: CostM = []([](0,3,5,7),[](4,0,9,6),[](2,1,0,5),[](-7,8,-2,0)),
        circuit_g([1,2,3,0], CostM, C).   

CostM = []([](0, 3, 5, 7), [](4, 0, 9, 6), [](2, 1, 0, 5), [](-7, 8, -2, 0))
C = 10


[eclipse 6]: CostM = []([](0,3,5,7),[](4,0,9,6),[](2,1,0,5),[](-7,8,-2,0)),
        C #= circuit([2,3,4,1], CostM) + 1.

CostM = []([](0, 3, 5, 7), [](4, 0, 9, 6), [](2, 1, 0, 5), [](-7, 8, -2, 0))
C = 11
