The process is called "minimization" and there is lots of software which
can do it. The original and famous program for this was called "Espresso".

I use a program named "SimpleSolver" where you enter the truth table,
and obtain the equations with a single click (you can find it easily in
Goole). That's how I generated the PLA dumps here:
