I was refactoring old code and encountered several IF conditions that were way too complex and long and I'm certain they can be simplified. My guess is that those conditions grew so much because of later modifications.
Anyway, I was wondering if any of you know of a good online simplifier I can use. I'm not interested in any specific language, just a simplifier that would take in for example:
((A OR B) AND (!B AND C) OR C)
And give me a simplified version of the expression, if any.
I've looked at the other similar questions but none point me to a good simplifier.
Thanks.
You can try Wolfram Alpha as in this example based on your input:
Try Logic Friday 1 It includes tools from the Univerity of California (Espresso and misII) and makes them usable with a GUI. You can enter boolean equations and truth tables as desired. It also features a graphical gate diagram input and output.
The minimization can be carried out two-level or multi-level. The two-level form yields a minimized sum of products. The multi-level form creates a circuit composed out of logical gates. The types of gates can be restricted by the user.
Your expression simplifies to C.
I found that The Boolean Expression Reducer is much easier to use than Logic Friday. Plus it doesn't require installation and is multi-platform (Java).
Also in Logic Friday the expression A | B just returns 3 entries in truth table; I expected 4.
