Having already read this question I'm reasonably certain that a given process using floating point arithmatic with the same input (on the same hardware, compiled with the same compiler) should be d...

I'm considering the feasibility of programming a multi-user RTS game (partly) in C++. What I quickly discovered, is that one hard requirement is that the game simulation must be fully deterministic...

I am developing a C application which needs floating-point determinism. I would also like the floating-point operations to be fairly fast. This includes standard transcendental functions not specif...

Don't quite understand determinism in the context of concurrency and parallelism in Haskell. Some examples would be helpful. Thanks

Floating point calculation is neither associative nor distributive on processors. So, (a + b) + c is not equal to a + (b + c) and a * (b + c) is not equal to a * b + a * c Is there any way to pe...

In a SQL SELECT statement, I'd like to execute a function that is deterministic for the scope of that SELECT statement (or transaction would be ok, too): select t.x, t.y, my_function(t.x) from t ...

Why is Query Version 2 so much faster? I suspect the DB Engine is calling the Table-Valued-Function "GetUsageStatistic" multiple times, so is there a way to tell the engine that "GetUsageStatistic...

This is my first question on this site, and I only have a basic mathematical understanding of RSA, so please bear with me! :) I'm writing a Java web application for my final year project at univer...

Now I have a really tricky thing with Oracle execution plans running havoc, when I use a DETERMINISTIC function on the right hand side of the LIKE operator. This is my situation: The Situation I ...

I have a problem which has an solution that can be solved by iteration, but I'm wondering if there's a more elegant solution using regular expressions and split() I have a string (which excel is p...

Is there any way in C# to mark a property as deterministic? The reason I ask is that I often find myself declaring a local variable and reading a property into it, instead of accessing the propert...

My supposedly deterministic program produces one of a few slightly different outputs on different runs. The input, compiler and computer are unchanging. I'm not sure which output is right bec...

I am reading the Java Hashmap documentation but I don't understand this sentence. Note that the iteration order for HashMap is non-deterministic. If you want deterministic iteration, use Lin...

I have been reading about Quicksort and found that sometimes it' s referred to as "Deterministic Quicksort". Is this an alternate version of the normal Quicksort ? What is the difference between a...

Whilst working on a recent project, I was visited by a customer QA representitive, who asked me a question that I hadn't really considered before: How do you know that the compiler you are using...

I'm looking for the format that Java uses to serialize objects. The default serialization serializes the object in a binary format. In particular, I'm curious to know if two runs of a program can s...

Situation: condition check in C++ or C# with many criteria: if (condition1 && condition2 && condition3) { // Do something } I've always believed the sequence in which these chec...

In the tradition of this question and in light of the documentation, how does one make this function deterministic: ALTER FUNCTION [udf_DateTimeFromDataDtID] ( @DATA_DT_ID int -- In form YYYYMMDD...

Related to this question, I decided to check the UDFs in my data warehouse (which should largely have been deterministic), and I found several which aren't which should be. For instance: CREATE F...
