Abstract: 
Based on deep results from coding theory, we present an deterministic algorithm that contructs a point set with dispersion at most $\eps$ in dimension $d$ of size $poly(1/\eps)*\log(d)$, which is optimal with respect to the dependence on $d$. The running time of the algorithms is, although super-exponential in $1/\eps$, only polynomial in $d$.
