On the Optimality of Spiral Search
Searching for a point in the plane is a well-known search game problem introduced in the early eigthies. The best known search strategy is given by a spiral and achieves a competi...

Approximation theorems for group valued functions
Stone-Weierstrass-type theorems for groups of group-valued functions with discrete range or discrete domain are obtained. We study criteria for a subgroup of the group of continuou...
