- | I'm a little behind on my news, but since last update, I've settled on a project and will move ahead with a study of parochial altruism and the evolution thereof with the hopes of pinning down a good fitness behavior that a robust program might engage in to ensure suitability in a resource-competitive environment. My presentation and the ensuing discussion helped reveal some potential pitfalls I might encounter like my approach to reproduction, | + | |

- | This evening | + | After a conversation with Prof. Ackley, it was concluded that my model needed a lot of simplification. So back to the drawing board I went, and implemented the changes he suggested. That done, and several wasted simulation runs later during which I realized I had some implementation errors in my model, I've gone back to running simulations. Now, instead of varying the amount of resources on the board, I am varying the threshold by which the Sytizens will engage in their genetic behavior. Parochials now have a single behavior. Altruists have another. Thus, PAs will engage in both. PNAs and NPAs will engage in one or the other, and NPNAs will engage in neither. Both genetic behaviors are tied to an energy threshold, below which they will not fire. For example, if set to 20, no Sytizen with less than 20 energy will share with or attack another Sytizen. This threshold is now what I am adjusting over runs. And holy crap, __I think I have a U-shaped curve__. |
- | This weekend I will be working on the Element_Creg tutorial and flesh out my element. | + | The bad news is, this has placed me very much behind. Now, my model description must be redone. My figure 1 redone. And I have many more lengthy runs to do before I can produce graphs 1 and 2. The bright side is that I am pretty much working |

I see PAs generally dominating across the board. What makes this somewhat dismaying is that the groups tend to have very little contact and interaction, |

- | Spent some time with Ezra in the CS lab playing with the fish and sharks. Best results so far only made it to 80 kAEPS. Have not hit on a stable solution yet. Strongly considering changing my research topic, but haven' | + | I've been working sporadically over the week, so I'm just going to compile everything into one update for the week: |
+ | |||
+ | Graphing: I've installed gnuplot on my usb-untu and wrote a bash script that will convert my data files into nice graphs that do a great job of telling the tale of a simulation at a glance. | ||
+ | |||
+ | The bad news is, this has exposed all the horrible things wrong with my Element_Sytizen. After doing several runs of of a single team only and seeing a predominance of one kind of classification, | ||
+ | |||
+ | Parochial Altruists: Attack outgroup with 0.5 chance of success, no longer get energy for this, but opponent still dies. On failure, 0.5 chance of dying from the attempt. | ||
+ | |||
+ | Parochial Non-Altruists: | ||
+ | |||
+ | NP-A: If NPA energy is over a threshold and a friendly has less energy than the energy surplus over that threshold, the NPA will give the friendly 1 RES worth of energy. | ||
+ | |||
+ | NPNA: Still just dancing. | ||
+ | |||
+ | This, along with some adjustments to global parameters (Increased breeding range to 4, RES pickup range to 2, Strike range to 2, Mutation odds to 1 in 250) the simulation runs now resemble something closer to sanity. Instead of looking like fish and sharks with swarms of colors chasing each other around the map, it now looks something more like Frobworld, with diffused dots chasing RES around the map and occassionally getting into scuffles with an outgroup. Runs with a single team now show more balance in categories (with the exception of NP-As which still tank fairly quickly, but at least appear | ||
