Summary

Benjamin A. Grayzel is a data scientist and software engineer who builds forecasts, models, and AI tools. He solved an open problem posed by Paul Erdős in 1997 (Erdős #659) using Gemini 3 Pro, verifying the solution through collaboration with Dartmouth mathematicians and publishing it on arXiv in 2026. He built a 2024 US presidential election forecast using simulation-based methodology and polling data, with his model identifying a Trump sweep of all seven swing states as the most likely outcome. This forecast proved accurate when Trump won all contested states. Grayzel is pursuing a Master's degree in Computer Science at Dartmouth College (graduating 2026) and holds a B.S. in Mathematics and Government from Dartmouth (2024).

Selected work

Solution to a Problem of Erdős Concerning Distances and Points2026 First complete solution to Erdős problem #659, resolving whether sets of n points in the plane can determine O(n/√log n) distinct distances while satisfying the constraint that every 4-point subset determines at least 3 distinct pairwise distances. Constructed using a lattice from a binary quadratic form and verified by Dartmouth mathematicians Peter Doyle and Peter Winkler.

2024 US Presidential Election Forecast2024 Comprehensive simulation-based forecast using polling-only methodology and historical election data from 1968 onward. Built in R with interactive maps, state-level and national odds, and sandbox tool for conditional probabilities. The model identified a Trump sweep of all seven swing states (Nevada, Arizona, Georgia, North Carolina, Wisconsin, Michigan, Pennsylvania) as the most likely outcome at 11.7% probability, which proved to be the actual 2024 result.

Benjamin's Substack Publication covering artificial intelligence and forecasting. Includes detailed breakdowns of election scenarios and analysis of predictive models.

Multi-Agent Framework Evaluation Designed and evaluated an agentic framework using MCP, LangGraph, and GitHub for LLM-based code generation and tool-use benchmarking, analyzing emergent behaviors in multi-agent systems.

State media tagging does not affect perceived tweet accuracy: Evidence from a US Twitter experiment in 20222025 Multi-author paper published in Harvard Kennedy School Misinformation Review examining the effect of media labels on social media content perception.
