Boolean expression solver/simplifier

a 夏天 提交于 2019-12-01 14:50:02
I am looking for an Boolean expression solver for very big (but not complex) algebra like: Boolsche Ausdrücke vereinfachen (Axiome) I would like to have some code (c++ or java [or libraries]) to simplify huge boolean expression. I haven´t found something. I just want to do some "simply" convertion like: a && ~a -> 0 a || a && (b || c) -> a But much longer. And I want to use symbolics (a, b, c1, d1..) not TRUE, FALSE, 0 or 1 at the moment. Thank you in advance. Edit: If I write it my self, I could use Javaluator and evaluate. When I have: (adb+c) && d I would like to start with multiply out.

javascript eval method

How can I watch variable values inside of javascript eval() method? And is it possible to "step into" and "step over" in eval method? For example, with a code like this: eval("if (true) { var a = 10; a += 20; alert(a); }"); I am more interested in debugging in IE9, but I would like to hear general principle as well. you can't inside the eval method. the code you give it is no code but a string. after the eval() then it becomes code and you can inspect it. This also depends on what tools you use to debug your script. In Chrome if you click Pause on exception, and execute your eval. it will

Matlab Attempt to execute script as a function

巧了我就是萌 提交于 2019-12-01 11:41:35
I have a matlab script, lets call it "master.m", that loads a file called "config.m". config.m contains all the variables used in master.m so that they can be changed easily without editing any of the code. Problem is, I am trying to get the main function in master.m to load config.m based on the user input. So basically I want the user to be able to specify the name of the file to load. For instance if config.m was called testing.m then the user could type at the matlab prompt: >> master(testing.m) and it would load up the file. BUT I can't figure out how to do this properly, I have looked

Dynamic execution of TypeScript in the browser

问题 I have TypeScript which asynchronously downloads another TypeScript/javascript module: (function (exports) { "use strict"; var path = require('path'); exports.convertData = function (data) { return "converted " + data; } })(typeof exports === 'undefined' ? this['converter.someConverter'] = {} : exports); During execution of my main app I receives this module as string and I have to use function convertData from there. So, I'm trying the following: eval(rendererScript); console.log(exports

getScript or eval in specific location?

I was wondering if eval (or some variant of jQuery's getScript) can be used to position external javascript in places other than the end of the DOM or at the head. I've tried: var head = document.getElementById("fig"); instead of var head = document.getElementsById("head")[0]; with var script = document.createElement("script"); script.text = $(".code").val(); head.appendChild(script); But I can't seem to get it to work regardless. (The code does work, but Firebug shows the code being replaced both at #fig and at the end of the page, right before the </body> tag. Basically the JavaScript

Use and implications of eval('expression') in MATLAB code?

问题 I was encountered with usage of function eval(expression) in somebody else's code in matlab: for example: for n = 1 : 4 sn = int2str( n) ; eval( [ 'saveas( fig' sn ', [ sName' sn ' ], ''fig'' ) ' ] ); end MathWorks stuff in Matlab Help pointed out that: Many common uses of the eval function are less efficient and are more difficult to read and debug than other MATLAB functions and language constructs. After this, I find usage of this function in many other program languages, so as Python,
