GresSuffurd uses a movement that from a (very very large) distance looks like WaveSurfing. The first version (0.0.3) is largely based upon the [[WaveSurfing/Tutorial|WaveSurfingTutorial]] written by [[Voidious]]. It will gradually improve until it is good enough for [[The2000Club]].

** do not evaluate stop-position when enemy is close (anti-ram)
* '''0.1.0''' (20061028) 
** slowing down when wallhit is eminent (but getting more predictable)
** using proper OnDeath (by [[David_Alves]]) and similar behaviour at onWin, meaning keep surfing until the air is safe

* '''0.0.6''' (20061019) 
** update 5 bins instead of 3 when hit (still no 'classic' binsmoothing)
** if direction does not matter, continue same direction (solved strange behaviour near wall)
* '''0.0.5''' (20061013) 
** Keep preferred distance, includes very simple dive-in protection
** Circle around enemy when there is no wave to surf
* '''0.0.4''' (20060925) 
** Surf wave until wavefront hits me, then start surfing next wave
** Use whole battlefield, no more buffer between the wall and my bot.
* '''0.0.3''' (20060919) 
** Initial version, largely based on the [[WaveSurfing/Tutorial|WaveSurfingTutorial]]

Ouch, I think I still have some work to do . . .   -- [[GrubbmGait]]

v0.0.4 seems good enough to release in the wild.  -- [[GrubbmGait]]

The score against WSCBotA is on level, seems like segmentation is the next thing to explore.  -- [[GrubbmGait]]

It hits the wall a lot, thats something to look into first, together with the right implementation of onDeath.  -- [[GrubbmGait]]

Still getting the HOT-avoidance optimal and the details right before tuning, read segmenting, to avoid non-HOT.  -- [[GrubbmGait]]

First time above GrubbmGrb! Against botA, botB and botC the results are acceptable, but I seem very vulnerable for a [[Bee]]-like GF-gun.  -- [[GrubbmGait]]

Checking the details I saw a relatively low score (93%) against bbo.RamboT where I expected a 99%. It turned out that for 3-4 ticks there was no surfable wave, the time it takes a wave to pass my bot. No surfable wave means no movement, which is not good against rambots/close fighters. In movement 0.1.6 (GresSuffurd 0.2.2) this is solved by creating a simulated wave when no surfable wave is available (instead of no wave available).  -- [[GrubbmGait]]

It turns out that, against the better bots, onBulletHitBullet happens approx 100-110 times per battle (is 3 times per round), so that information is really welcome.  -- [[GrubbmGait]]

Wow, that often? Thanks for posting that. =) Now I *really* want to fit that into [[Komarious]]... -- [[Voidious]]

Some nuancing: the above was with robocode 1.2.5_Alpha. With 1.1.2 it happens 'only' ~70 times (2 per round). Don't know why, have to ask [[Fnl]].  -- [[GrubbmGait]]

Well, a 3:2 ratio doesn't seem like that big a deal to me... But in 1.2, I seem to be getting zero BulletHitBullets ever. A sample match of Dookious vs [[Roland]] gave 67 in Robocode 1.07 and 0 in 1.2. :-\ -- [[Voidious]]

Yeah, I know that the implementation in 1.06/1.07 was not really well (using a line with fixed 8 length I think). In version 1.2.1 (according the version.txt) this has been replaced by a new algorithm. I think that in v1.2 it just was really buggy. I don't have a problem with a better solution, although it might have a minor influence on the performance, as long as it is logical and bugfree. I tested against WaveSerpent with 1.0.6 (59 bullethitbullet), 1.1.2 (63) and 1.2.5_Alpha (106). It seems that currently the most stable/bugfree version is still 1.1.2/1.1.3, but this may change with 1.2.5 (memory issue!)  -- [[GrubbmGait]]

I like it when things turn out the way they should be: rolling the surfingstats does perform much better against PM and GF-guns, but looses points in the rumble, see 0.1.8.  -- [[GrubbmGait]]
