Multi-Task Optimization over Networks of Tasks

arXiv:2604.21991v2 Announce Type: replace Abstract: Multi-task optimization is a powerful approach for solving a large number of tasks in parallel. However, existing algorithms face distinct limitations: Population-based methods scale poorly and remain underexplored for large task sets. Approaches that do scale beyond a thousand tasks are mostly MAP-Elites variants and rely on a fixed, discretized archive that disregards the topology of the task space. We introduce MONET (Multi-Task Optimization over Networks of Tasks), a multi-task optimization algorithm that models the task space as a graph:

Why this matters
Why now

The proliferation of complex, multi-task AI systems necessitates more efficient optimization methods beyond current population-based or fixed-archive approaches.

Why it’s important

Advanced multi-task optimization can unlock new efficiencies and capabilities for AI systems, making large-scale AI deployment more feasible and powerful.

What changes

The ability to model task spaces as graphs, rather than relying on discrete archives, fundamentally alters how large sets of tasks can be optimized.
