Constructive dimension and constructive strong dimension are effectivizations of the Hausdorff and packing dimensions, respectively. Each infinite binary sequence A is assigned a dimension dim(A) in [0,1] and a strong dimension Dim(A) in [0,1].

Let DIM^alpha and DIMstr^alpha be the classes of all sequences of dimension alpha and of strong ... more >>>

A bipartite graph is biplanar if the vertices can be
placed on two parallel lines in the plane such that there are
no edge crossings when edges are drawn as straight-line segments.
We study two variants of biplanarization problems:
- Two-Layer Planarization TLP: can $k$ edges be deleted from
a ... more >>>

There are two approaches to solving a new supervised learning task: either
analyze the task independently or reduce it to a task that has already
been thoroughly analyzed. This paper investigates the latter approach for
classification problems. In addition to obvious theoretical motivations,
there is fairly strong empirical evidence that ... more >>>
