My understanding of a tournament selection is:
For a given tournament size, t , randomly select t individuals from the population and determine the winner of that tournament as the individual with the largest fitness function value.
My question is:
Is there a difference between 'Binary Tournament Selection' and 'Tournament Selection', or are they interchangeable terms?

You have a value, lets call it k which determines of how many candidates you pick the best one for each parent you want to chose. This value is often 2 and in this special case we can also call it binary tournament selection. Tournament selection is just the broader term where k can be any number >= 2.
Fitness Proportionate Selection is one of the most popular ways of parent selection. In this every individual can become a parent with a probability which is proportional to its fitness. Therefore, fitter individuals have a higher chance of mating and propagating their features to the next generation.
A new selection method, entropy-Boltzmann selection, for genetic algorithms (GAs) is proposed. This selection method is based on entropy and importance sampling methods in Monte Carlo simulation. It naturally leads to adaptive fitness in which the fitness function does not stay fixed but varies with the environment.
The selection pressure is the degree to which the better individuals are favored: the higher the selection pressure, the more the better individuals are favored. This selection pressure drives the GA to improve the population fitness over succeeding generations.
