Quick examples

Boolean formula

Follow these steps in order to create, compile and execute a simple program.

Create a file named main.cpp

#include "BoolFunc.h"
#include "CnfConverter.h"

int main () {
  Formula a = BoolFunc::newLit("a");
  Formula b = BoolFunc::newLit("b");

  Formula c = a + b;
  Cnf tseitin = CnfConverter::tseitin(c);
  tseitin.print();
}

This program converts c into a CNF using the Tseitin transformation. The output will be

3 -1
3 -2
1 2 -3
3

Pseudo-Boolean optimisation

Introduction

Features

This library has functionalities for two type of problems: Boolean logic and Pseudo-Boolean minimisation problems. Its aim is to simplify the representation of the representation of this problems and solve them.

Boolean formula

Check Boolean formulas for full documentation.

  • Boolean formulas representation
  • CNF encodings
    • Tseytin transformation
    • Extracting primes transformation
    • Mix transformation
  • Execute a SAT Solver
  • BDD conversion

Pseudo-Boolean optimisation

Check Pseudo-Boolean minimisation for full documentation.

  • Pseudo-Boolean minimisation problems representation
    • Pseudo-Boolean constraints
    • Cost function
    • Pseudo-Boolean minimisation problem
  • How to solve it
    • Search strategy
      • Binary
      • Linear
    • Solver
      • Without timeout
      • Timeout per SAT solver execution
      • Global timeout

Download

It is recommended to download always stable versions:

$ wget https://github.com/marcbenedi/SAT-tfg/archive/v1.1.zip
$ unzip  v1.1.zip

Install

$ chmod +x installer.sh
$ ./installer.sh

Compile and execute

The fastest way to compile the file is placing it inside the library folder such as SAT-tfg/main.cpp

Then execute

make main

This command compiles, links and executes the program. Alternatively, this three steps can be executed separately:

make compile_main
make link_main
./main
