Deadlock Dev Uses ChatGPT to Help With Matchmaking Code

Valve's upcoming MOBA-hero shooter, Deadlock, recently underwent a matchmaking system overhaul. A key element of this revamp involved leveraging the power of ChatGPT, as revealed by Valve engineer Fletcher Dunn on Twitter (X). Dunn credits ChatGPT with identifying the Hungarian algorithm as the ideal solution for Deadlock's matchmaking challenges.

Addressing Player Concerns

Deadlock's previous MMR-based matchmaking had drawn significant criticism from players. Reddit threads were filled with complaints about unevenly matched games, pitting experienced players against newcomers. One player commented on the disparity in skill levels between teammates and opponents, highlighting the frustration of consistently facing stronger adversaries while their team lacked comparable expertise.

ChatGPT's Role and Developer Perspective

Dunn openly shared his reliance on ChatGPT, stating it's become an indispensable tool, constantly open in a dedicated Chrome tab. He enthusiastically promotes ChatGPT's capabilities, countering skepticism about AI's potential to replace human programmers. While acknowledging the potential for reduced human interaction, he emphasizes the positive impact of AI in accelerating development and problem-solving.

The core issue involved finding an algorithm suitable for a scenario where only one party (players) has preferences. ChatGPT successfully identified the Hungarian algorithm as a solution for this bipartite matching problem, optimizing team and opponent assignments based on player preferences.
