Simplifying logical expressions

[john]

What methodologies are there for simplifying logical expressions?

My old friend, a software engineer seemed to use 2 methods.

One seemed mathematical in nature, like solving an equation.

The other method was graphical he draw a chart and then x'd out the bits
that did not matter.

Any ideas on good resources for simplifying logical expressions.

He is gone now. Wish I'd paid more attention.
