Combinatory Models and Symbolic Computation
We introduce an algebraic model of computation which is especially useful for the description of computations in analysis. On one level the model allows the representation of alge...

On Khachiyan's algorithm for the computation of minimum-volume enclosing ellipsoids
Given A := {a1, . . . , am} ⊂ Rd whose affine hull is Rd, we study the problems of computing an approximate rounding of the convex hull of A and an approximation to the minimum ...

Laplacian-based consensus on spatial computers
Robotic swarms, like all spatial computers, are a challenging environment for the execution of distributed consensus algorithms due to their scale, diameter, and frequent failures...
