Or, more briefly: f (a) ≥ f (x) for all x in the interval. In other words, there is no height greater than f (a). Note: a should be inside the interval, not at one end or the other.

WebA function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = { (a,b) for all a ∈ A, b ∈ B} WebIn fact you can view the purpose of value-based RL is learning a good heuristic function (the value function) from the more sparse reward function. If you already had a good heuristic function then you may not need RL at all. You may need to compare very different parts of the outcome in a single reward function. flame thrower drones electric best
