FormulaBuilder

Contains helper functions for building Formula.

The basic building blocks of formulas are true/false literals and propositional variables. You get a PropVar with propVar and bool2formula provides an implicit conversion from Boolean to True/False.

Once you have a Formula instance, you can combine it using its methods matching regular boolean operators. You can also use n-ary combinators or and and.

import Formulas._
import FormulaBuilder._

val a: PropVar = propVar("a")
val b: PropVar = propVar("b")
val f: Formula = and(a, (!a || b), (!b || false))

implicit def bool2formula(b: Boolean): Formula

Returns the formula representation of a Boolean.
Returns the formula representation of a Boolean.
b
a Boolean literal to wrap into a formula
returns

Builds a disjunction of formulas.
fs
sequence of formulas to be combined
returns
a new Formula instance that represents the disjunction of the input formulas
def propVar(prefix: String = "P"): PropVar

Returns the formula representation of a propositional variable.
Returns the formula representation of a propositional variable.
The propositional variable is always fresh and unique, there is no need to use a different name for different invocations. You need to maintain a pointer to the returned instance if you want to refer to it later in your code.
prefix
a String prefix to the name of that variable
returns
A fresh and unique propositional variable with a name starting with prefix
