+Traditional '''GuessFactor Targeting''' is the specific combination of [[GuessFactors]] and [[Segmentation|Segmented]] [[Visit Count Stats]]. It uses these algorithms to [[Statistical Targeting|statistically]] generate a good firing angle. It is one of the most popular and successful methods of [[:Category:Targeting|targeting]] in all of [[Robocode]]. Alternatives to GuessFactor Targeting include [[Dynamic Clustering]] and [[Pattern Matching]].

+Note that despite its name, GuessFactor Targeting is not the only targeting method to use [[GuessFactor]]s.

-[[User:Paul Evans|Paul Evans]] and [[User:David Alves|David Alves]] were the first [[:Category:Bot Authors|authors]] who implement some forms of GuessFactor targeting, though their first systems did not yet use [[segmentation]]. The following description by David (from 2003) and the paper by Paul that he mentions were what first brought GuessFactor Targeting to the rest of the Robocode community:
+=== Early description ===
 <blockquote>
-My targeting is similar to the [[SandboxLump]] / [[SandboxDT]] method. Here's how it works.
+My targeting is similar to the [[SandboxLump]]/[[SandboxDT]] method. Here's how it works.
 :* Calculate how far forward the other bot could go if it suddenly went top speed forwards for as long as it would take my bullet to reach the other bot. Call this Point A.
 :* Calculate how far backward the other bot could go if it suddenly went top speed backwards for as long as it would take my bullet to reach the other bot. Call this Point B.
-Now take a guess between -1 and 1 at where the bot is going to be. -1 would mean going straight back and ending up at B, 1 means going straight forward and ending up at A. 0 means sitting still. I just keep track of how well different numbers work and fire with the best one. You can find a better description (with code!) at [[http://www.aqre94.dsl.pipex.com/robocode/guessfactor.shtml this url]]. However notice that the algorithm that Lump uses (the bit where he says he uses the bot's current acceleration) is a bad idea, because it won't hit bots that sit still for a long time and then suddenly hit the gas. He fixed this when he came out with DT. (And I fixed it in [[Duelist]]! :-D) However, pretty much any targeting method will work well enough as long as it isn't simple linear or circular targeting, because some bots (like [[Fermat]]) will guess where you would fire if you used circular and dodge accordingly.

+=== Evolution and refinement ===
 While the same fundamental principles have applied since its creation, several key factors have helped GuessFactor Targeting become increasingly powerful and popular over the years:
 * Perhaps the most important was the addition of [[segmentation]], which allows separate sets of statistics to be collected for different firing situations. Things like proximity to walls, current velocity, and distance from the firing bot have a large impact on what GuessFactor will hit the target, so segmenting your stats on these attributes helps a lot.
 * [[Kawigi]], through his [[open source]] bot [[FloodMini]] and the [[GuessFactor Targeting Tutorial]] that he authored, showed many people how to implement GuessFactor Targeting.
-* There have been many incremental improvements to GuessFactor Targeting guns by a variety of authors, including: refining what attributes make the best segments, using Virtual Guns systems with multiple GuessFactor Targeting guns, using multiple Visit Count Stats buffers (and summing the values or switching between them), and using [[Maximum Escape Angle/Precise|precise maximum escape angles]] in GuessFactor calculations.
