Choke point. In military strategy, a choke point (or chokepoint) is a geographical feature on land such as a valley, defile or a bridge or at sea such as a strait, which an armed force is forced to pass, sometimes on a substantially narrower front and therefore greatly decreasing its combat power, to reach its objective.
In this context, a canonical form is a representation such that every object has a unique representation. Thus, the equality of two objects can easily be tested by testing the equality of their canonical forms.anonical form can also mean a differential form that is defined in a natural (canonical) way. In computer science, data that has more than one possible representation can often be canonicalized into a completely unique representation called its canonical form.
(Historically, according to religious law) 1. A standard way of writing a formula. Two formulas such as 9 + x and x + 9 are said to be equivalent because they mean the same thing, but the second one is in canonical form because it is written in the usual way, with the highest power of x first. Usually there are fixed rules you can use to decide whether something is in canonical form.
