Towards Exploration-only, Exploitation-only Hybrid Search Techniques

    Summary:

    Our research on thresheld convergence has shown how concurrent exploration and exploitation can interfere with subsequent exploration.

    Description:

    We are currently developing techniques for exploration only, and these techniques subsequently need another technique for exploitation. We are combining these techniques in a new hybrid model that starts with an initial phase of exploration only before a distinct transition to a phased of exploitation only.
