boolean-logic

All - I have found something called "Simple Solver" located here: http://home.roadrunner.com/~ssolver/syn.html and you can download it here http://www.softpedia.com/progDownload/Simple-Solver-Download-103308.html My question is: Is Simple Solver the only one out there that solves digital circuits for you given inputs / outputs you want? Is there other software besides Simple Solver that will solve digital circuits? Would appreciate all / any advise. Look at Logic Friday 1 . This is an interactive tool so handle / solve boolean expressions defined as function table, expression or network of

Consider the following method in Java: public static boolean expensiveComputation() { for (int i = 0; i < Integer.MAX_VALUE; ++i); return false; } And the following main method: public static void main(String[] args) { boolean b = false; if (expensiveComputation() && b) { } } Logical conjunction (same as &&) is a commutative operation . So why the compiler doesn't optimize the if-statement code to the equivalent: if (b && expensiveComputation()) { } which has the benefits of using short-circuit evaluation ? Moreover, does the compiler try to make other logic simplifications or permutation of

Should be a simple question for the C# experts here. I basically want to check if one value or another is TRUE, a wild stab at the code is below: if ((Boolean.Parse(staff.getValue("Male")) | Boolean.Parse(staff.getValue("Female"))) { // is true } Is this correct? Thanks If EXACTLY ONE should be true then it is: var male = bool.Parse(staff.getValue("Male")); var female = bool.Parse(staff.getValue("Female")); if (male ^ female) { //is true } Sounds like you're looking for the logical OR. if(condition1 || condition2) { } Use the || (double pipe), logical OR. bool isMale = Boolean.Parse(staff

How to create a logical OR with logical AND, and logical NOT? Check De Morgans's laws . You are looking for the Substitution form . P OR Q = NOT( (NOT P) AND (NOT Q) ) It's De Morgan's Law : A OR B = NOT ( NOT A AND NOT B ) Truth table for A OR B: A B X 0 0 0 0 1 1 1 0 1 1 1 1 Truth table for the De Morgan equivalent: A B !A !B (!A AND !B) !(!A AND !B) 0 0 1 1 1 0 0 1 1 0 0 1 1 0 0 1 0 1 1 1 0 0 0 1 Like not (not x and not y) ? Pretty simple: A || B = !(!A && !B) Using DeMorgans law. The Negation of (Not A "And" Not B) 来源： https://stackoverflow.com/questions/8374895/how-to-make-logical-or-with

Say I have code like this: boolean ret = a() && b() && c() && d() && e(); Usually e() is only called if all other calls a()-d() return true. Is there maybe some compiler or JVM option to disable short circuit evaluation, so e() would be called always, regardless of other functions' results? Basically I am doing UAT of huge system and need to test e(), however setting up environment and scenario that assures all a(), b() etc. return true is extremely painful... EDIT: ok, I guess using bit AND instead of logical one could provide SOME sort of workaround, however ideally I am looking for a

For n variables, there exists 2^(2^n) distinct boolean functions. For example, if n=2, then there exists 16 possible boolean functions which can be written in sum of product form, or product of sum forms. The number of possible functions increases exponentially with n. I am looking for an algorithm which can generate all these possible boolean rules for n variables. I have tried to search at various places, but have not found anything suitable till now. Most of the algorithms are related to simplifying or reducing boolean functions to standard forms. I know even for the number of rules become
