Sanguijuela/Evolution History
Contents
Sanguijuela 0.5
Released: 2 April 2008
Codesize: 635
Ratings Battles: 3108
| Rumble | Position | Points |
|---|---|---|
| General | 1631.88 |
What's new
- Choose each round between Linear (90%) and Circular (10%) movement and targeting
- Change the calculation of the best initial Radar direction using Smash method by Starrynte. My code got the same results but with more codesize.
Comments
It was not good idea but I wanted to try it. Looking at the comparison between 0.3 and 0.4, Linear is better in a 76% of the conflictive cases. If I choose between Linear (90%) and Circular (10%) strategy then
p(ok)= p(s=L)*P(ok|s=L) + p(s=C)*P(ok|s=C) = P(ok)*P(s=L) + P(ok)P(s=C) =0.76*0.9 + 0.24*0.1 =70.8
So Sanguijuela lost 5.2% of the conflictive cases but I thought that adding this variability in the strategy could be interesting. The 0.3 (only Linear) has still better performance.
Sanguijuela 0.4
Released: 24 March 2008

| Micro | 72 / 209 | 1645.37 |
What's new
- Change Radar from WideLock to NarrowLock.
- Change linear movement and targeting to circular. The predicted position of the enemy use 8 as velocity for the movement and 11 for the targeting.
Comments
Involution. After some testing I thought that a circular movement and targeting could be better than linear but, in general, it seems to be false. The previous version appears and disappears misteriously in the RoboRumble so I could make these statistics.

Comments
I have tested Sanguijuela's ramming performance (V0.2) with the archived results of RamBotChallenge2K6 (two years ago) and it takes the 3rd place.
| Bot | Ramming Percentage | Overall Score |
|---|---|---|
| MaxRisk 0.6 | 24.65 | 46.39 |
| SledgeHammer 0.22 | 21.42 | 45.26 |
| Sanguijuela 0.2 | 21.86 | 44.11 |
| ARAMtocles 0.3 | 20.65 | 44.05 |
| NanoDeath 2.56 | 23.60 | 43.85 |
Sanguijuela 0.1
Released: 5 January 2008
Codesize: 869
Origin
- Linear Ramming and Targeting.
- It calculates the best direction to start scanning.
- It chooses ramming with the anterior or the posterior suckers depending on host's starting position.
