 We made this decision based on the impressive results obtained in the latest SMT solving competition, and based on the results showed by Frank et al. in [ETHBMC](https://www.usenix.org/system/files/sec20fall_frank_prepub_0.pdf).
 That being said, greed offers a modular architecure and implementing support for a new solver backend is quite straigthforward.
 
-By default, we give unlimited time to the solver to solve the constraints. However, it can be sometimes helpful to timeout after a certain amount of time. You can do this by using the option `SOLVER_TIMEOUT`. Keep in mind that, when the timeout fires, the state will be reported as `errored`.
