**Randomizers** are logic blocks which have a 50% chance to change state when given either a high or a low logic signal. They can be used in series or parallel to create more complex probabilities.

## Contents

## Item Description

"This block produces random results when activated. Each time it receives any signal (true or false) it changes it’s state by a 50:50 chance."

## Usage

Randomizers function in a similar manner to Flip Flops, in that when on, they remain on until caused to change state again. The key difference, of course, is that a Randomizer will not always change state when given an input. The chance, per input, of a Randomizer changing state is 50%. It is relevant to note that, for a Randomizer, an "input" actually constitutes any change in state of a block which is linked to it, *not* just high signals. This means that a Button produces two inputs to a Randomizer; one when the Button is activated, one when it turns off again.

While a single Randomizer has a constant 50% chance of changing state, more complex probabilities can be created by linking many Randomizers to a single logic gate.

Connecting several Randomizers (all with the same input) to a single AND-Signal should result in an output probability (from the AND-Signal) of (**P** = **0.5**^**n**). For the AND-Signal to activate, of course, all of the Randomizers must turn on simultaneously; this behavior can be reasonably compared to multiplying along the branches of a probability tree to find the probability of a particular outcome.

Conversely, linking many Randomizers to an OR-Signal will result in an increased chance of activation. Since the OR-Signal will turn on when *any* of the Randomizers activate, the probability of an output is much higher than the same circuit using an AND-Signal. This configuration will result in an output probability (from the OR-Signal) of **(P = 1 - 0.5^n**) and will approach 1 as the number of randomizers increase. (*Disclaimer: the exact behaviors of Randomizers are not yet fully tested, and this analogy may prove incorrect*)

Increasingly complex probabilities can be created by combining various layers of such circuits, in varying proportions.
