Score: 1979.24 after 900. Another dissappointing release.

Score: 1989.16 after 1056. This was very disappointing as I thought this version was better than previous versions. It seemed to test better. Ah well.

September 26, 2004: Ver 0.82 -- Now bug fixing the .59.3 line. First bug fix: (int)Math.round(latVShotTime?/3) can be rounded to 3. This muddied my movement related latvel stats.

Score: 2019.86 after 341

Score: 1989.46 after 144.

September 25, 2004: Ver 0.81.1 -- Bug fix. Not sure what it was though.
RECALLED I had to download the bot and run it locally to find the error. Sorry to flail like that.

September 25, 2004: Ver 0.81 -- Adding back in functionality removed when I rolled back. Looking to see if it makes a difference or not.
RECALLED! Something is not right here. When you see this:

Fighting battle 10 ... jekl.DarkHallow 0.81,nic.Nicator 2.4
RESULT = nic.Nicator 2.4 wins 6063 to 488
you know something is not right.

September 24, 2004: Ver 0.80 -- Rollback to .59.3 to prove that it will not be as good. PEZ was right again.
Score: 2022.34 after 707.

Currently on my todo list:

What's special about it?

It is my first WaveSurfer.

Great, I want to try it. Where can I download it?


How competitive is it?

It is in the rumble now so time will tell.

How does it move?


How does it fire?

Uses a guess factored targeting system copied and slightly modified from BlackPearl.

How does it dodge bullets?

It surfs.

How does the melee strategy differ from one-on-one strategy?

one-on-one only at this point.

How does it select a target to attack/avoid in melee?

No melee capability in there yet.

What does it save between rounds and matches?

No data is saved.

Where did you get the name?

From a song by the Grateful Dead: I would rather be in some Dark Hallow, where the sun don't ever shine, than to be in some big city, in a small room with a girl on my mind. I know it has no bearing on RC but I love the Dead so.....

Can I use your code?

Code is in the jar. It is not very tight right yet but feel free. Use the RWPCL please.

What's next for your robot?

Not sure yet.

Does it have any WhiteWhales?

None right now. More to come later I am sure.

What other robot(s) is it based on?

It started as BlackPearl, which is based on Jekyl.

Comments, questions, feedback:

"Can you believe I still hit the walls?" Try this:

 setMaxVelocity?(150.0 / getTurnRemaining?());
Combine that with a large enough wall margin and you should be fine. For example, use 150.0 / getTurnRemaining?() and don't pick destination points that are within 25 pixels of the walls. Using a higher number than 150 will prevent you from slowing down so much when you turn, but will require a larger wall margin to ensure that you don't hit walls. --David Alves

But this is a risky business for a WaveSurfer unless you also build it into your movement predictor. CassiusClay too hit walls at times. I think it is my WallSmoothing algo that don't take into account that it takes quite a while to reverse direction. Jim, check if maybe DH has decided to reverse direction just before it hits the wall and see if you share the same glitch. -- PEZ

So build it into your movement predictor. ;-) --David Alves

Nah. It's complicated enough as it is. -- PEZ

Right now I am testing all of my "improvements" from the .70 line. It seems that for the most part they were anything but. Once I am done with that I will move on to new things. One of the first orders of business will be to protect myself from firing enemy waves when they collide woth the wall. I am not sure how to work that out though. -- jim

November 2 2004 (CET) - Welcome back man. I've missed ya! -- PEZ

Lets see how I feel in a week. I was pretty burned out. This version will finally beat DT over 500 rounds. It is the only test I ran too. -- jim

So much for me having the top US bot. :-( Oh well. Congrats! --David Alves

Thanks. It was really just old code. Nothing new. Some small bug fixes. Still plenty of room between my score and infinity for you to slip into ;-) -- jim

Cool man, welcome back. ;] -- iiley

Pulsar is waking us all up. Isn't he? =) You found 10 points there. Good work. -- PEZ

I would not read too much into it. I just had the day off work due to a snow storm in the region. Like I said last time, lets see how I feel in a week. -- jim

How do you weight your visit stats compared to hit stats? Do you roll the stats? How fast? I find it interesting that you gain lots of points by segmentation of the visit stats while I lose a few... -- PEZ

Hey PEZ. I segment my stats like this:

hits[accelIndex][outIndex][(int)Math.round(myLatVel)/3][distIndex] fastHitsBuf[0][0][0]

The distance index is 5 buckets of 180 pixels, the out index is 5 buckets of 45 pixels. I am currently using 29 GuessFactors. I got a 6 point boost going from 41 to 29. I roll the stats using AndrewsCoolWay. My gun stats and my movement stats are indentical in most ways. My gun stats have more segments (a closingIndex and a timeIndex) and are not rolled. I have tried not rolling my movement stats but after about 15 or so turns I seem to get stuck between some local maxima and oscilate in place. As you are well aware, thats not so good =^> -- jim

Cool. And how (if) do you weigh the visit stats? Mine has weight 45. Unsegmented hit stats has weight 50 and most segmented hit stats weighs 100. I roll my movement stats using Paul's RollingAverage. -- PEZ
