Mathematics of Boosting Agentic Communication (MATHBAC) Proposers Day

Other / Unclassified

This document announces a Proposers Day for the anticipated Mathematics of Boosting Agentic Communication (MATHBAC) program, sponsored by the DARPA Defense Sciences Office (DSO). The event is scheduled for April 21, 2026, in Arlington, VA, and will also be webcast. Advance registration is required for both in-person attendance and webcast viewing.

• Introduce the research community to the MATHBAC program vision and goals.
• Explain the mechanics of a DARPA program and its milestones.
• Encourage and promote teaming arrangements among potential organizations.

The MATHBAC program aims to develop next-generation Agentic Artificial Intelligence Platforms that systematically evolve to transform scientific discovery for defense. It will focus on the science of AI communication, leveraging mathematics, systems, and information theory to govern AI agent collaboration and information sharing.

DARPA encourages teaming before proposal submission. Options include:

• Attendee List: Contact information (name, organization, email) shared with other attendees (opt-in).

• Proposer Profile List: A one-page profile detailing contact information, technical competencies (agentic AI, small science models, math/info/systems/data science), and desired expertise. Profiles are due by April 14, 2026, and will be consolidated and emailed to participants.

• Date: April 21, 2026, 11:00 a.m. - 2:00 p.m. (Eastern Time)

• Location: Arlington, VA (in-person) and webcast.
