CaDiCaL Simplified Satisfiability Solver
|
|
===============================================================================
|
|
|
|
The goal of the development of CaDiCaL was to obtain a CDCL solver,
|
|
which is easy to understand and change, while at the same time not being
|
|
much slower than other state-of-the-art CDCL solvers.
|
|
|
|
Originally we wanted to also radically simplify the design and internal data
|
|
structures, but that goal was only achieved partially, at least for instance
|
|
compared to Lingeling.
|
|
|
|
However, the code is much better documented and CaDiCaL actually became in
|
|
general faster than Lingeling even though it is missing some preprocessors
|
|
(mostly parity and cardinality constraint reasoning), which would be crucial
|
|
to solve certain instances.
|
|
|
|
Use `./configure && make` to configure and build `cadical` and the library
|
|
`libcadical.a` in the default `build` sub-directory. The header file of
|
|
the library is [`src/cadical.hpp`](src/cadical.hpp) and includes an example
|
|
for API usage.
|
|
|
|
See [`BUILD.md`](BUILD.md) for options and more details related to the build
|
|
process and [`test/README.md`](test/README.md) for testing the library and
|
|
the solver.
|
|
|
|
The solver has the following usage `cadical [ dimacs [ proof ] ]`.
|
|
See `cadical -h` for more options.
