Finding solutions of systems of boolean equations by exhaustive

computing a Groebner basis, except in special cases where the latter
is particularly easy.

+The libFES library is presently only able to deal with polynomials in 64
variables. Performing a full exhaustive search over 64 variables will
take a **long** time. The number of variables can be artificially
reduced to 64 by specializing some of them.
