given the following text: "The strong point of the presentation was the presenter’s ability to effectively
communicate complex information in a concise and understandable manner. He
accomplished this through the use of visual aids in the form of presentation
slides to support his message and illustrate the concepts he was talking about.
Specifically, the parts of game theory that were mentioned in the presentation
and the workings of specific algorithms were explained in a clear manner. Overall
I feel like the presenter was skilful in his way of communicating information in
a concise and easy to grasp manner."
