  1. GECCO Papers • Same research group, different lead authors • Same conference • Paper 1: Embodied Distributed Evolutionary Algorithm (EDEA) for on-line, on-board adaptation of robot controllers • Paper 2: “We propose and experimentally validate racing as a technique to cut short the evaluation of poor individuals”

  2. GECCO Papers • Both use On-Board, On-Line (encapsulated) evolution • Robots learn in real time in the real world. • Testing an individual requires giving it control of the robot. • Paper 1 distributes learning across multiple robots • Paper 2 uses racing: shortens testing time of poor robots.

  3. µ+1 algorithm • Population of µ individuals • Generate one new individual (+1) • Evaluate new individual and compared to worse individual in the population • If the new individual is better, have it replace the worst individual.

  4. GECCO Papers • EDEA Paper has more detailed introduction • Both use similar test problems (same problem descriptions) • Similar parameters and parameter tables • Both papers actually use simulations • Results are presented very differently

  5. Racing • Alpha and Beta (used to determine confidence that challenger is not better) • 3 values of each: 9 permutations • Risk that one permutation will appear better through luck • Even if one permutation is better for a given problem, which one should you use for your problem???

  6. Racing - Conclusion • “Of course, our findings very likely depend on the tasks we investigated as well as our choice of controller – as far as we know, the field of evolutionary robotics lacks a taxonomy of robot tasks or controllers that allow for a meaningful generalisation of our findings. Still, the results are promising and warrant further research into racing as a method of improving performance in online evolutionary robotics”

  7. From Homework • Smith and Doe found … • In Roe et al. it was found … • Research by Fred and George showed …

  8. General Writing - Outline “This paper is divided into two parts – Part I and Part II – they describe the basic algorithms of each paradigm, and depict similarities and differences between them. The algorithms are presented in a descriptive instead of a mathematical form.” What is the rest of the paper going to look/sound like? Are there any new results?

  9. General Writing - Outline • Outline paragraph at the end of the introduction: “This paper is structured as follows. Section II explains … Section III presents … Section IV …” • Alternative, actually explain something: “We begin by presenting related research (Section II). Next we explain how our experiments are designed to test our hypothesis that… (Section III). …”
