Detailed Description

Example: Magic sequence

Find a magic sequence of length $n$. A magic sequence of length $n$ is a sequence

\[x_0,x_1, \ldots, x_{n-1}\]

of integers such that for every $i=0,\ldots,n-1$:

  • $x_i$ is an integer between $0$ and $n-1$.
  • the number $i$ occurs exactly $x_i$ times in the sequence.

See problem 19 at http://www.csplib.org/.

Note that "Modeling and Programming with Gecode" uses this example as a case study.
