This project is part of our school (42) cursus. It aims to create a solver for simple boolean algebra. (https://cdn.intra.42.fr/pdf/pdf/6852/en.subject.pdf)
The executable is made to be launched with a config file passed as arguement.
Usage:
./expert-system config_file
This project use the 1.39.0 version of Rust, but newer version of the language should work too.
To install Rust: https://www.rust-lang.org/tools/install
To install the 1.39.0 or Stable: https://doc.rust-lang.org/nightly/edition-guide/rust-2018/rustup-for-managing-rust-versions.html
cargo build --release should compile the project and put the executable
in ./target/release
The configuration file has 3 main parts.
- Rules definitions
- Facts assignations
- Queries
The rules definition use the following syntax : FACT OPERATOR FACT => FACT
The possibles operators are : + (and), ^(xor) and | (or).
ANDs operators (+) are allowed in the right side of the rule.
Parenthesis may be used.
The ! (not) operator may be used to negate a fact or a operation group
(in front of parenthesis)
The + (and) and ^ (xor) have a higher priority over the |(or)
Example:
A + B | (A ^ C) => D
The Facts assignations start with =.
It list all the facts that are to be set on true at the beginning of the computation.
Example:
=ABD
Queries are used to ask expert-system the value of variables. A config file
can have multiple queries at different places.
Example:
?ABD
