Re: Newbie Pattern matching Question

Hi,
not having done such thing in robocode, computing the distances of
vectors, and the tuple (heading change, velocity) can be seen as such,
can be done by computing vT x A x v, with vT being the difference
vector in horizontal, v in vertical, and A some symmetric matrix. In
the simplest form, A is a diagonal matrix, this means the expression
will evaluate to w1*v1^2+w2*v2^2, with w1 and w2 being some weights
and v1 and v2 the elements of the vector, so in your case heading
change and velocity. If you compute those values you might find the
vector that is next to the one you are comparing to, but you may need
some runs to find good values for w1/w2. Fails if there is no good
matrix for all vectors, but usually a first try, especially in the
simplified version.

Hope that helps,
Johannes
