An IPASIR interface to connect applications to Mallob's incremental on-demand SAT solving
Execute make. This produces the library libipasirmallob.a which provides all IPASIR functions as defined in src/ipasir.h.
The interface will select randomly among the available API paths provided by Mallob in the files /tmp/mallob.apipath.*.
Now you can link IPASIR applications with the library file libipasirmallob.a to obtain an application which uses Mallob as a backend SAT solver.
For more information on linking IPASIR applications with IPASIR solvers, see the IPASIR Github repository.
Mallob must run in the background in order to use this interface.
For each call to solve(), this IPASIR bridge creates a JSON request file and puts it into the new/ subdirectory of the API directory and awaits an answer in the done/ subdirectory.
For correct functionality, it is essential that your application properly calls ipasir_release for each IPASIR instance it created.
Otherwise, stale job nodes that are reserved for the dead job may accumulate and eventually clog the entire system.
- The termination method is not functional yet because Mallob does not yet support arbitrary interruption of a certain incremental job "from the outside".
- No clauses are reported even if a callback is supplied: Mallob does not export clauses to the outside (yet).
