multithreading - Non-deterministic programming languages -


I know that you can do something in a prologue 

  some functions (list ): - Some other functions (X, list) doSomethingWith (X)% and so on

This list will not be repeated on every element; , With a different execution for each possible value, it can separate "machines" (using multiple threads, backtracking on a thread, X some other functions (X, List) causes to return the truth!
(I do not know how this happens, but it is not important for the question)

My question is: Other non-manual programming languages ​​are out there? It seems that non Neutrality is the simplest and most logical way to implement multi-threading in a language with temporary variables, but I've never done this before - Why is not this technique more popular?

< P> Nodederminism is unpopa because it makes it difficult to think about the consequences of your programs, and in fact the ethical hang (as

  • Concurrent ML, which has information about communication

  • Language of Gerard Holzman In fact it is possible to use Nondeterminism and discover the entire state space when it can.

    And certainly any multithreaded language behaves nondeterministically if threads are not synchronized, but this is absolutely something which is difficult for reason & mdash; And why it is so difficult to implement this efficient, accurate locked data structure.

    By coincidence, if you want to achieve equality, then you can get the same thing by using a simple map function like a pure functional language Haskell is one of the reasons Google MapReduce functional Is based on languages.

    sql - dynamically varied number of conditions in the 'where' statement using LINQ -

    I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

    asp.net mvc - Dynamically Generated Ajax.BeginForm -

    I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
