-Amazing: I make an off-hand comment about how I'm a loser who doesn'​t know how to debug and not 4 hours later, a tutorial gets posted on logging and debugging. IT'S LIKE MAGIC!+
-Today'​s impediment is that I do not have a million dollars...+[[:​people:​chris_symonds:​project_submission|Final Project Page]] has been posted.
-Worth a shot. AnywayI've implemented the genetically-specific behavior of my Sytizens, and thanks to the magic of LOG.Debug ​I've ironed out some (not all) kinks in my element. I need to be able to incorporate some randomness into the creation of the element, specifically in GetDefaultAtom function. I have an sos in to Trent on the best way to get a nicely seeded prng in that function.+===15-Nov-2014 01:​09:​07PM-0700=== 
 +Okso here's where I'm at:
-Next up: Implement breeding. Now where is the Barry White function...+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 behaviorParochials 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 runsAnd holy crap, __I think I have a U-shaped curve__.
-===27-Sep-2014 09:​51:​34PM-0600=== +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 solely on this over the weekend, but I wonder if that will be enough time...
-Stellar programming achievements today:+
-   * Managed to get my Sytizens to take full account of their surroundings +===08-Nov-2014 10:​05:​54AM-0700=== 
-   * Managed ​to get them moving in a direction biased towards food (think) +I completely forgot ​to make an update last week, so I guess I'll lump it in with this weeks, and attempt ​to keep it concise.
-   * That's pretty much it +
-   * Oh, at one point I realized I was adding negative integers into an unsigned int variable +
-   * Ah yes, and at one point I tried to divide by 0+
-So, not much progress today. I still have tomorrow, and the rest of what I need is essentially variations on things ​I'​ve ​since figured outso I'​m ​hoping ​for a faster pace tomorrow.+   * I've completed 20 simulation runs of Paralta; 4 levels of increasing scarcity with 5 runs each. The results are not terribly exciting or interesting. I see PAs generally dominating across the board. What makes this somewhat dismaying is that the groups tend to have very little contact and interactionparticularly in the more scarce environments ​and the behavior and fitness ​of a PA is rooted in his interactions with outgroups. So I don't even know what this result means other than the likely root being an inherent flaw in my model.  
 +   * Regardless, ​I'​ve ​done a write up of my model for presentation in next class. It's fairly bullet-happyand I'​m ​not sure that's an appropriate thing for a research paper, as I don't remember reading any with this many bullets. I guess the class will judge. 
 +   * I'm pretty sure I have the worst Figure 1 ever. Even having put my paper into IEEE format will not make this figure 1 look respectable. It's a train wreck. 
 +All in all, the outlook is iffy. On the bright side, were I to do a project like this again, I would be much more comfortable in knowing the kinds of bumps to expect, and a better sense of where the pitfalls lie. That's a good thing.
-Impediments:+===26-Oct-2014 09:​30:​47PM-0600=== 
 +I've been working sporadically over the week, so I'm just going to compile everything into one update for the week:
-   ​* ​I'm concerened ​that even without conflict, ​my Sytizens tend to die very quickly now matter how kind I am or how much RES I have floating around. Sometimes it seems these things die surrounded by food, so I'm not sure what's going on there. +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.
-   * I'm hesitant to have these guys gang up in any way, as that will likely be their death warrant given how quickly they can run out of energy and DREGs are slow to replace it unless I just saturate ​the map with RES. +
-   * Without being able to do any kind of debugging, I'm flying blind here.+
 +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,​ I concluded something must be wrong in the implementation. After going through the code, there were not only issues with genetic behavior, but with breeding and movement as well. After some refactoring of the broken stuff, I tried to take Professor Ackley'​s advice and simplify the genetic behavior as much as possible. The following behavior algorithms are now in effect:
-===27-Sep-2014 10:16:​04AM-0600=== +Parochial AltruistsAttack outgroup with 0.5 chance of successno longer get energy for this, but opponent still diesOn failure0.5 chance ​of dying from the attempt.
-Forgot to update last nightso this is last night'​s update: Managed to get the good Sytizens of Paralta walking around and eating res and dying when they run out of gasThis was no small endeavorand there were more than one "​Aha"​ moments when I finally understood how some basic mechanisms ​of MFM work (like realizing that I have to keep re-writing ​the active Sytizen to the window if I want the new state to take effect, even if the Sytizen does not move). My poor wife had to endure me shouting at my Sytizens all night "Why won't you die?! I want you to die!" She looks at me funny now.+
-{{ :people:​chris_symonds:​dyingsytizens.png?​nolink&​500 |Yes...yes...die my little pretties...die!}}+Parochial Non-Altruists0.5 chance of stealing 1 RES worth of energy from outgroupThe PNA does not get to keep this energy if successfulOn failure: 0.5 chance of losing 1 RES worth of energy.
-TodayI'll be forging ahead to get as many interesting behaviors as I can out of them before demo on Monday.+NP-A: If NPA energy is over a threshold and a friendly has less energy than the energy surplus over that thresholdthe NPA will give the friendly 1 RES worth of energy.
-===21-Sep-2014 08:29:​11PM-0600=== +NPNAStill just dancing.
-Tutorial done. Element_Sytizen draft is done. Didn't get to push ahead on research of Tom Ray as I'd hoped. Getting Ubuntu/MFM working at home was much more of an endeavor than I'd fooled myself into believing. I guess there'​s always next week. Until there isn't.+
-===20-Sep-2014 02:​15:​22PM-0600=== +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 outgroupRuns with a single team now show more balance in categories ​(with the exception of NP-As which still tank fairly quicklybut at least appear on the board now.)
-Just a celebratory news update: as of the timestamp I finally have the mfm built and running on an ubuntu partition at home. (MFM is painfully slow, however, at ~25AER) Now to figure out emacs and do the tutorial.+
-===19-Sep-2014 07:46:22PM-0600=== +{{:people:chris_symonds:​res200b1_09.png?​direct&​300|}}
-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,​ as well as some great improvement ideas in having PA elements rove around in bands.+
-Today I had a great primer in developing for the MFM via Trent'​s ​boot camp. I think I've got my work cut out for me and it's a good thing that I only have essentially one element to develop.+Here'​s ​an example run with 1 team only, RES produced at 1 in 200
-This evening I am going to attempt getting a usb drive set up with Ubuntu to be able to boot from it.+{{:​people:​chris_symonds:​team_one_graph_01.png?​direct&​300|}} 
-This weekend I will be working on the Element_Creg tutorial and flesh out my element.+And here's one with 2 teams, RES produced at 1 in 200.
-===07-Sep-2014 04:​27:​05PM-0600=== +I think I'​m ​in good shape, ​and so am now cautiously transitioning ​to my science hat.
-Still playing catch-up from 5 days out of town. Too early to feel like I'​m ​drowning. Perused the options for ALife researchers ​and chose Dr. Thomas Ray. He seems really interesting;​ especially with lines like "My current research: The diverse set of psychoactive drugs collectively represents a rich set of tools for probing the chemical architecture of the human mind." I read that one sentence and said "​Sold."​ +
-I've found no additional time to get into the labs at school and play with the fishes. I guess I'm left floundering at 80kAEPS.+
-===27-Aug-2014 10:17:54PM-0600=== +===22-Oct-2014 08:54:16PM-0600=== 
-Read Professor Ackley's paper [[http://​​~melaniem/​courses/​CAS09_files/​chap5.pdf|Altruism ​in the Evolution of Communication]]Was relieved to discover that it was different angle of altruism than was thinking ofHoweveram still considering what lessons might be carried over to a study of a population of individuals sharing resources in varying degrees of altruismAlsoattempted ​to get MFM running through ​putty session which was laughably unsuccessful+Finished reading Maley's paper in preparation for my defense next classHaving never defended ​paper in this manner before, ​I'm not sure what to expectMy brother'​s recommendation is to put my back to the cornerdrop the paper at my feet, and swing my arms around wildly, all while making extremely loud bird calls to confuse would-be attackersSo between that and carefully studying the paperI should hopefully be able to put up good defense.
-===27-Aug-2014 04:​06:​33PM-0600=== 
-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'​t hit on any bright ideas yet. Trying to think outside the box, but I'm not even really sure what the box looks like... ​
