I'm Xinyu Chen, a new graduate student here. I like logic and rule-processing so I think maybe these things are about artificial intelligence. Alife is a interesting area because 'life' is so abundant and everything seems to be 'alive'. No matter what it is, a particle, a molecule, a people or a society, etc. Even some non-material phenomena are like living things: a language, a custom, a trend of fashion, a religion…. Let's try to understand some of them and find out their U-curves.

• This is my final deliverables page.
• Thanks for Professor Ackley and all my wonderful classmates!

• Draft paper_cxy.pdf

• Crit3 presentation
• Model description graph

• Change my Story. Can I get more STRONG? Model Description

• Change my Story. Use Perfume instead of Stench. First try on Model Description.
• Thanks for Taylor's help! I took his Algorithm office hour for ALife!
• Professor 's paper is really a challenge.

• Talked with professor. I knew how incoherent my idea was. OH, Weak Claim is so difficult to implement!
• Get focused on Aura. Fix the abstract.
• Thanks for Trent helped me out with the MFM2.0.10 and the swap thing!
• Hutton's paper is really relevant with my cells. This paper exactly let me know how naive my idea is!

• Made a ppt version of William Grey Walter.
• Prepare for the paper-attack. Thanks a lot to Lucas!

• Add some materials to William Grey Walter

• Fix the abstract.
• 
• Leave reproduction problem aside for a while. Let Bad Cell emits Aura first.

• Fix the abstract.
• Try a lot on reproduce. Still didn't work well.

• Let the outmost layer of cell reproduce. But they will not stop. Maybe this can be useful for emiting Aura.

• Give colors to different layer of Cell. Now they looks like tree rings

• Ｍerge Cell-Core and Cell-Wall into one element:Cell
• Make an element Jumper. It will jump away from each other. Maybe useful for cell division behavior.

• Add Cell Wall boundary-test, LOG and debug helps!
• Make a little abstractof my project. Thanks for Chris and Lucas. I learned a lot from you guys!

• A Pioneer of Robotics and Artificial Life: William Grey Walter

• 1T challenge:
  • 1st attempt is a box-with holes. The box provide some shelter for fish. It works up to 40+K.
  • There are two big opens easy for fish/shark to enter the box;
  • Also two opens make it easy to come out of the box.
  • I hope this can create some pattern of rotation but it didn't.
  • More boxes can work better. They can separate the fish/shark, which will give the system more
  • robustness.
  • 2nd attempt is a mixture of Dregs, sorters, fish and shark.
  • Dregs will try to keep the Occupied Site Density to about 35%. But fish/shark
  • outgrow Dreg's control
  • Sorters can separate fish/shark more randomly.
  • the 2nd method works better but it didn't survive more than 80K.

• Project idea:Dymanic Medicine Molecue Router

• tried the shark game by add some walls and mazes. Thanks James!
• Tried to leave tiny crevices on the walls so some luck fishes can escape.
• Did not survive more than 12-13 K.
• I wish I could manipulate the maze when sharks were surrounding fishes!
• I need walking-walls! Someone talked about Movers but I can't remember who. Did Prof A mention it?
• tried to put some Movers. They break down Walls and scatter them into many tiny walls. Chaos!
• the ocean is filled with sh, fi, mv, and 'bricks'. It goes well to 120K.
• When I tried to put these words here, sharks died out around between 130-140K. What happened to them?

• struggling with MATLAB and math homeworks
• got the notification from Dave
• rushed here to fill up a slot

• Trying to make a page here.
• Trying to install an Ubuntu into my PC.
