Typically digital system will encode bits with uniform probability to maximize the entropy.
Real votes are not independent, and do not have uniform probabilities.
The principle of vacant places is a rule for updating those uniform probabilities as one learns about the deal during the auction and the play.
If is chosen randomly (with uniform probability), then c 0 with probability 1.
For example, individuals in a social network are not connected to other individuals with uniform random probability.
Less accurate, if the knowledge of the possibilities is very unstructured, thereby necessarily having more nearly uniform prior probabilities (by the principle of indifference).
His estimates used Bayes' theorem with a uniform prior probability and assumed that his sample was random.
To actually send a message a node chooses randomly (with uniform probability) from all nodes in the network and forwards the message to them.
(However, analysis is usually simpler if the randomizing function implements each possible mapping with uniform probability.)
But a stronger condition is often needed in which every output occurs with almost uniform probability.
