void Gecode::circuit ( Home  home,
const IntVarArgs &  x,
IntPropLevel  ipl = IPL_DEF 
)

Post propagator such that x forms a circuit.

x forms a circuit if the graph with edges $i\to j$ where $x_i=j$ has a single cycle covering all nodes.

Supports domain (ipl = IPL_DOM) and value propagation (all other values for ipl), where this refers to whether value or domain consistent distinct in enforced on x.

Throws the following exceptions:

Post propagator such that x forms a circuit.

x forms a circuit if the graph with edges $i\to j$ where $x_{i-\text{offset}}=j$ has a single cycle covering all nodes.

Supports domain (ipl = IPL_DOM) and value propagation (all other values for ipl), where this refers to whether value or domain consistent distinct in enforced on x.

Post propagator such that x forms a circuit with costs y and z.

x forms a circuit if the graph with edges $i\to j$ where $x_i=j$ has a single cycle covering all nodes. The integer array c gives the costs of all possible edges where $c_{i*|x|+j}$ is the cost of the edge $i\to j$. The variable z is the cost of the entire circuit. The variables y define the cost of the edge in x: that is, if $x_i=j$ then $y_i=c_{i*n+j}$.
