Query: Simultaneously Evolving Deep Reinforcement Learning Models using
  Multifactorial Optimization   In recent years, Multifactorial Optimization (MFO) has gained a notable
momentum in the research community. MFO is known for its inherent capability to
efficiently address multiple optimization tasks at the same time, while
transferring information among such tasks to improve their convergence speed.
On the other hand, the quantum leap made by Deep Q Learning (DQL) in the
Machine Learning field has allowed facing Reinforcement Learning (RL) problems
of unprecedented complexity. Unfortunately, complex DQL models usually find it
difficult to converge to optimal policies due to the lack of exploration or
sparse rewards. In order to overcome these drawbacks, pre-trained models are
widely harnessed via Transfer Learning, extrapolating knowledge acquired in a
source task to the target task. Besides, meta-heuristic optimization has been
shown to reduce the lack of exploration of DQL models. This work proposes a MFO
framework capable of simultaneously evolving several DQL models towards solving
interrelated RL tasks. Specifically, our proposed framework blends together the
benefits of meta-heuristic optimization, Transfer Learning and DQL to automate
the process of knowledge transfer and policy learning of distributed RL agents.
A thorough experimentation is presented and discussed so as to assess the
performance of the framework, its comparison to the traditional methodology for
Transfer Learning in terms of convergence, speed and policy quality , and the
intertask relationships found and exploited over the search process.
