On the Approximability of the Minimum Test Collection Problemble by the greedy algorithm. In particular, for instances with test sizes at most . we derive an .(log.) approximation. We show APX-hardness of the version with test sizes at most two, and present an approximation algorithm with ratio . for any fixed ε > 0.

U. Trockel,M. Hennericins may reveal paradigms worthwhile revisiting. With the help of some of those scientists who have contributed to it, the editors sketch the history of this scientific journey and ask them for inspirations for future directions of galaxy research..978-3-319-80941-0978-3-319-31006-0Series ISSN 0067-0057 Series E-ISSN 2214-7985

Enrico Grazziution of this problem has been obtained in the form of a stationary running wave—a plastic shockwave propagating in an unperturbed half-space. The solution is a generalization of the earlier obtained analytical solution for a medium with the Mohr-Coulomb plasticity condition. A formula for determini
