Key developments during this time was a physical symbol system, that became also the basis for mathematical symbols used in algorithmic presentation today, developed. This provided the mathematical and logic foundations for presenting algorithms, along with a way to standardize their expression, that later developed AI's presentation in discussing theoretical insight.<ref>For more on the early history of algorithms and mathematical logic that created concepts of AI, see: Nilsson, Nils J. 2010. <i>The Quest for Artificial Intelligence: A History of Ideas and Achievements</i>.
