问题 Given a set of clauses, I want to first check whether they are satisfiable. If they are, I want to simplify them and create a CNF, eg., (a OR b) ^ (NOT b) should simplify to: a ^ (NOT b). I'm only working with propositional formulas. I've tried to use Java SAT4j library for doing this. It can show me whether the set of clauses are satisfiable, but doesn't seem to have any method for returning me a simplified CNF. What can I do for simplifying CNF efficiently? Are there any Java or Python

问题 I have a sample combinatorial circult in Verilog where I can follow the instruction to do logic synthesis and generate blif file. However, what I need is to generate the CNF formula out of the circuit. Tools such as ABC only allows to generate from combinatorial miter (i.e., with 1 output). I tried the yosys instruction "sat -dump_cnf FILE", and indeed I am able to generate a CNF file. However, I am not sure how to map variables in the CNF with I/Os in the circuit. Have anyone studied the

问题 I am developing a 3.x based Eclipse RCP application. In the part of application, I am implementing Common-navigator plugin of Eclipse itself, in order to display resources in the workspace. I'have created the navigator view shown below: But I would like display only one tree child element. More specifically, I only want clause folder and its elements to be shown. What is the accurate way to do it? 回答1: Add dependecy of org.eclipse.ui.navigator if not exists in plugin.xml. Add extension point

问题 We have added a new custom view to our Eclipse Kepler environment. The new view is similar to the Navigator view and the Project Explorer view, except that it filters and reorders the displayed resources according to our special needs. After creating the custom view using the Eclipse Common Navigator Framework (CNF), we find that there are no edit items such as Copy nor Paste in the popup context menu, and they are disabled in the regular dropdown menu. So now we need to add them. Several

问题 I have a CNF expression like this and I want recast it to 3-CNF: (a+b+c+d)(~a)(~b+d)(a+b+~d) Does anyone know how I can do that? 回答1: A 3-CNF is a Conjunctive Normal Form where all clauses have three or less literals. To obtain such a form for your expression, you could translate the expression into a nested Boolean expression where all operators (and, or) have two operands: t1a = (a+b) t1b = (c+d) t1 = t1a + t1b t2 = (~a) t3 = (~b+d) t4a = (a+b) t4 = t4a + ~d t5a = t1 t2 t5b = t3 t4 t5 = t5a

问题 If PCFG is like, NP -> ADJ N [0.6] NP -> N [0.4] N -> cat [0.2] N -> dog [0.8] What will be CNF form? Will it be the following? NP -> ADJ NP [0.6] NP -> cat [0.08] NP -> dog [0.32] or somethings else? 回答1: NP -> ADJ NP [0.6] NP -> cat [0.08] NP -> dog [0.32] Your answer is correct because you need to get the same probability for the result by applying both the original and the converted set of rules (in CNF). 来源： https://stackoverflow.com/questions/39769119/what-will-be-cnf-form-of-this
