chuffed-flatzinc 0.13.1-1 (armhf binary) in ubuntu oracular

 Chuffed is a state of the art lazy clause solver designed from the
 ground up with lazy clause generation in mind. Lazy clause generation
 is a hybrid approach to constraint solving that combines features of
 finite domain propagation and Boolean satisfiability. It combines
 some of the advantages of finite domain constraint programming (high
 level model and programmable search) with some of the advantages of
 SAT solvers (reduced search by nogood creation, and effective
 autonomous search using variable activities).
 .
 Chuffed only supports 3 different propagator priorities. Chuffed
 implements a number of global propagators (alldiff, inverse, minimum,
 table, regular, mdd, cumulative, disjunctive, circuit,
 difference). It also only supports two kinds of integer
 variables. Small integer variables for which the domain is
 represented by a byte string. And large integer variables for which
 the domain is represented only by its upper and lower bound (no holes
 allowed). All boolean variables and boolean constraints are handled
 by the builtin SAT solver.
 .
 The solver, when run with lazy clause generation disabled, is
 somewhat comparable in speed with older versions of Gecode. The
 overhead from lazy clause generation ranges from negligible to
 perhaps around 100%. The search reduction, however, can reach orders
 of magnitude on appropriate problems. Thus lazy clause generation is
 an extremely important and useful technology.
 .
 This package provides a FlatZinc implementation, to be used as a
 MiniZinc backend.
