The Role of Artificial Intelligence in Mathematics 🤖
Artificial intelligence has become a prominent topic in our culture, arousing both optimism and skepticism about its impact on our future. While some envision AI as humanity's savior, others foresee apocalyptic tribulations. However, looking at the current state of artificial intelligence, it becomes clear that it is pointing us in a specific direction. But what does this mean for the field of mathematics?
Mathematics and Automata systems have a long history together. From the controversies surrounding the Four Color theorem to modern proof assistant software, technology has enabled remarkable feats in the realm of math. However, one barrier remains: Can an autonomous system possess the creativity necessary to make Meaningful contributions to the field?
This is where Graffiti comes into play. Graffiti is a computer program specifically developed to make conjectures in the field of graph theory. Since its inception in the mid-1980s, Graffiti has generated numerous conjectures, with some even crossing over into the field of chemistry. As an undergraduate, I had the privilege of working with Dr. Simeon Fejalowitz, one of the architects of Graffiti, during an independent study. Under his guidance, I explored and attempted to prove some of the conjectures suggested by Graffiti.
To better understand these conjectures, it's important to have a grasp of graph theory itself. Graph theory involves the study of graphs, which can be imagined as collections of connected dots called vertices. As we delve into this fascinating field, we encounter various concepts such as vertex, edge, face, degree, distance, and classifications of different types of graphs like trees, stars, and planar graphs. While many results and theorems are already established, graph theory remains an abstract yet highly applicable domain, especially within computer science.
One of the simple Graffiti conjectures I had the opportunity to explore is as follows: If T is a tree graph, then the average degree of T is no more than its average distance. This conjecture poses an interesting challenge, and to approach it, we will first attempt to break it by finding a counterexample. We will calculate the degrees of each vertex and the distances between all pairs of vertices in the graph, searching for any discrepancies. However, in doing so, we stumble upon an intriguing observation regarding star graphs.
Before delving into the main result, let's prove a useful claim: Out of all tree configurations for a set of vertices, a star configuration produces the minimum total distance. To understand why this is the case, consider a star graph with n vertices. It becomes evident that there are precisely n-1 pairs of vertices at a distance of one from each other, with all other pairs being at a distance of two. If there were a graph with a smaller total distance than that of a star, some pairs that are two apart would need to be reduced to a distance of one, resulting in a graph with at least n pairs of vertices at a distance of one. This would violate the definition of a tree and contradict the Euler characteristic formula.
Now, let's turn our attention to the final result. If T is a tree, then its average degree is no more than its average distance. Using the handshaking lemma, which tells us that the sum of vertex degrees is twice the number of edges, we calculate the average degree for T. On the other hand, the average distance is determined by considering all pairs of vertices and calculating their distances. By utilizing previous results and closely examining the square of the quantity n-1, we can establish that the total distance of T must be greater than or equal to (n-1)^2, which ultimately confirms our conjecture.
In conclusion, artificial intelligence, when applied to mathematics through programs like Graffiti, opens up new possibilities for generating mathematical conjectures. While AI might not possess human-like creativity, it can assist mathematicians in discovering intriguing directions and fruitful results. As the field of graph theory continues to advance, the collaboration between human mathematicians and AI programs holds great potential for pushing the boundaries of mathematical exploration.
