Cognitive domain

In the con­text of cog­ni­tive sci­ence, a ‘do­main’ is a sub­ject mat­ter, or class of prob­lems, that is be­ing rea­soned about by some al­gorithm or agent. A robotic car is op­er­at­ing in the do­main of “legally and safely driv­ing in a city”. The sub­part of the robotic car that plots a route might be op­er­at­ing in the do­main “find­ing low-cost traver­sals be­tween two nodes in a graph with cost-la­beled edges”.
