Hi all, I'm working on a simple tutorial, and I'd like to randomly generate the positions of the red and green boxes in the accompanying images anywhere inside the dark gray area, but not in the white area. Are there any particularly elegant algorithms to do this? There are some hackish ideas I have that are really simple (continue to...
I am trying to create a lottery simulator. The lottery has 6 numbers, the number generated must be between 1 - 49 and cannot be in the next number generated. I have tried using the OR function but I'm not entirely sure if I am using it properly. Any help would be great. Thanks. Public Class Form1 Private Sub cmdRun_Click(ByVal sender A...
How do I use a random number generator that gives bits (0 or 1) to simulate a fair 26-sided die? I want to use a bitstream to pick letters of the English alphabet such that the odds of any one letter coming up is the same as the odds of any other letter (I know real words aren't like that and have specific frequency distributions for eac...
While this may look like homework, I assure you it's not. It stems from some homework assignment I did, though. Let's call an undirected graph without self-edges "cubic" if every vertex has degree exactly three. Given a positive integer N I'd like to generate a random cubic graph on N vertices. I'd like for it to have uniform probabilit...
I need to create a random character generator that return a single character. The character should range within the letters of the alphabet, numbers 0 through 9, and some characters like ,.?/-. Any example would be appreciated. ...
Hello all, i would like to effeciently generate positions for objects on a given surface. As you probably guessed this is for a game. The surface is actually a 3D terrain, but the third dimension does not matter as it is determined by terrain height. The problem is i would like to do this in the most effecient and easy way, but still g...
I'm trying to write a random date of birth generator for a date of birth between 25 and 50 years ago. I'm stuck with Java 1.4 and am attempting to accomlish this via java.util.Calendar (yes, yes, I know I should be using the Joda libraries). Here's where I'm at: private static long ONE_YEAR_AS_MILLISECONDS = 365*24*60*60*1000; private...

Dear all, I have asked a question about random generating -ve +ve decimal value here: http://stackoverflow.com/questions/3206563/how-to-generate-random-ve-ve-decimal-with-php But now i have another more challenging problem. May I know how can I generate random integer with -ve +value with a different set? like from -552 to 2200 as an e...
What is the most efficient way to generate a large (~ 300k vertices) random planar graph ("random" here means uniformly distrbuted)? ...
I have seen some examples of the random int in Objective-C, but all people are complaining about the same number sequence every time the application runs. I have read about seeding the random number, but I am not sure what that even means. How can a random number be generated differently every time, even after application has relaunche...
Hi all, As a teacher I am looking to create a random name generator to use with my classes. I don't know much but I am willing to learn. I want my random name generator to be able to load class lists from an external csv or txt file - I want the random name generator to be able to recognise the time and load the pre-defined class for tha...
Hello, Trying to get this to function, randomly chooses 1 of the 3 color choices. Is rand only capable of generating numbers? or Numbers/letters in a series. <div onclick="location.href='<?php the_permalink() ?>';" style="cursor:pointer;background:#<?php echo rand (DDCA73, A0AA47, ADBAE1)?>;" class="post bg thickbox" id="thickbox post-...
i have to define a variable that i am using in a program but i want the variable to change from int to char. example #include <iostream> #include <cstdlib> int main() { int l=rand(); char x; std::cout<<"this program makes a random char or number enter n for a number or c if you want a letter\n"; std::cin>>l>>"\n"; ...
I'm trying to generate a string of a random length which consists out of random chars. To do so I have this code: class Program { static void Main(string[] args) { for (int i = 0; i < 1000; i++) { MyString test = new MyString(); test.Random(); Console.WriteLine(test.Value); ...
I need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this: Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String 'Create a new StrinBuilder that would hold the random string. Dim randomString As ...
I have a DataGrid that shows orders that belong to product. I want to have a generated SolidColorBrush that is unique to each product. Update I need these colors to be solid and distinctive, or at least to be ordered in a distinctive way, i.e. there shouldn't be black, blue, green as these 3 colors can be confused with each other. Bes...
Hello, I would like an efficient utility to generate Unique sequences of bytes. UUID is a good candidate but UUID.randomUUID().toString() generates stuff like 44e128a5-ac7a-4c9a-be4c-224b6bf81b20 which is good as long as you don't need to transmit it over http, in which casa the dashes need to be removed. I'm looking for an efficient w...
