MicroBot Wave Surfing

Anyone have 10TB of memory and hard disk to spare? I need that to perform my own microbot wave surfing. The large part of Wave Surfing is precise prediction, which nonetheless can't fit in micro. I wonder if I cached all the prediction and just access it at runtime. Now I roughly calculated. Let see, I restricted the location, absBearing, velocity and distance to all integer. Total possible location on the map is 764*564 = 430896 locations, multiply by 360 absBearing, ~950 distance, 17 velocity. Saves in short (2 bytes), contain x and y will result in around 764*564*360*950*17*2*2 = 10020917376000 B 9786052125 KiB = ~9,556,692 MiB = ~9,333 GiB = ~9.114 TiB.

Anyone have ideas how can I reduced those number? If I use 80*60 possible locations, 36 possible absBearing, 17 velocity and 19 possible distance, it still cost 43MB Note that this need to be preloaded into the robot, not calculating on-the-fly.

Hey Nat. I've seen that you are trying to use melee surfing. For dodging the bullets you can get the distance to closest bullet and create some points in that distance. It works well in melee but it dowsn't work very well in one on one because it uust goes to a safe point. Not the safest one. It is also very easy to use.

So I have been gone for about a year and a half, and want to go back to this game again (guess you can never left robocode completely).

Basically, what innovations/technological breakthrough did I miss?

Not sure if you noticed, but we transitioned to LiteRumble when DarkCanuck's server went down. Sheldor and I took the nano crown with a collaboration bot, Yatagan. Nz.jdc updated LittleBlackBook's table, and wrote his own table-driven bot. They are both above Yatagan in the nanorumble, but they are sort of cheesy because they react to enemy name, not enemy behaviour. DrussGT now has a bullet-shielding mode which is tried at the beginning of each match. Chase finally found a bug in Seraphim and its APS now matches its strong PL score. I improved Neuromancer's 1v1 score a lot, and got it to 1st in melee.

I'm sure I've missed a lot of other stuff.

I just couldn't give up on that robot. Even though I wanted to. I might have to go back and look over other old robots of mine and fix errors in those, and re enter them into the rumble. Like Tyrra.

Welcome back!

• RoboRumble 1v1 crossed 1,000 participants.
• I wrote RoboRunner, a new multi-threaded battle runner, and Skotty wrote RoboJogger, a GUI version of it.
• We upgraded to MediaWiki 1.19. So the Twitter feed and bigger font got reverted and we still haven't fixed it. Need to upgrade PHP before moving past that.
• Personally, I've written/released a game called BerryBots in that time, which spawned from the Raspberry Pi discussion here at the RoboWiki. Right now working on replay support, which is almost ready (sample).

I restarted working on Roboflight again for a bit, made it easier to write stuff in, currently on the back burner though. Not sure if you were around for it, but I also finally added a proper gun that I wrote to Nene. Aside from that a lot of robots have been updated in general.

Thank you. It seems that I does miss a lot :)

This ought to cover a lot.

Skilgannon's and my bot Yatagan did quite well in the NanoRumble. My bot EpeeistMicro has a perfect PWIN (PL percentage) score in the MicroRumble. I still haven't started writing a minibot yet, but I do plan to sometime in the current century. :)

Would this be a good extension to install on this wiki?

I'm open to it if people want it. Would you have preferred to login with OpenID?

Only problem I see is it requires MediaWiki 1.21 and we're on 1.19. I think I stopped there because it required upgrading PHP, but we should do that and upgrade MediaWiki sometime anyway.

I am not even sure why he made this post on Nat's talk page. That said, I never found OpenID to be that easy to use (or to setup to use).

It would be easier for the end user and probably to setup to use one of the many "Login in X" systems. Where X is Twitter, Google, Facebook, or what have you.
