 Returns next regular expression for line starting from spos.

Protected Attributes

const int * spec
 Specification to be used.
BoolVarArray b

Picture specifications

A specification is given by a list of integers. The first two integers (w and h) specify the number of columns and rows respectively. Then w + h groups of integers follows. Each group is started by the number of integers it contains (n), followed by n integers specifying the sizes of the stretches of markers in that row/column.

Detailed Description

Example: Nonogram

This example solves nonograms. A nonogram is composed of a matrix of markers. For each row/column there is a specification on how many groups of markers (separated by one or more unmarked spots) and their length. The objective is to find a valid assignment, which incidentally may also produce a pretty picture.

See problem 12 at http://www.csplib.org/.

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