Here: The result is either red, green or blue. The method is not applicable to other sets of colors though, where you’d have to build a list of all the colors you want to choose from and then use random.choice to pick one at random.
This works by returning a plus something, where something is between 0 and b-a which makes the end result lie in between a and b.
I have a task to randomly chose 100 element from a population of alpha list [a,b,c,d] with corresponding frequency (probability) [0.1, 0.3, 0.2, 0.4]. There are many different ways to do it. But here I want what returned after this function call (suppose there is one) is a list of the number of elements chosen. … Read more
32767 + 1 is a power of 2 Binary representation of numbers uses powers of 2. So, in an 4-bit structure, 0101 is 2^0 x 1, 2^1 x 0, 2^2 x 1, and 2^3 x 0 which is 5. The MSB is used for sign and unsigned integers.
This is a simple example to generate randoms between 1 to 6, I think you can figure the rest
You can use the random functionality included within the additions to the standard library (TR1). Or you can use the same old technique that works in plain C:
The easiest way for your understanding:
rand() can be used to generate pseudo-random numbers in C++. In combination with RAND_MAX and a little math, you can generate random numbers in any arbitrary interval you choose. This is sufficient for learning purposes and toy programs. If you need truly random numbers with normal distribution, you’ll need to employ a more advanced method. This will generate a number … Read more
Best approach, no crazed values, distributed with respect to the representable intervals on the floating-point number line (removed “uniform” as with respect to a continuous number line it is decidedly non-uniform): (*) … check here for subnormal floats Warning: generates positive infinity as well! Choose exponent of 127 to be on the safe side. Another approach which will give … Read more
