Ordering clone libraries in computational biology.

We consider a probabilistic model, due to Lander and Waterman and to Alizadeh, Karp, Newberg and Weisser, for the physical mapping of DNA molecules. Within this model, we answer precisely a question of Alizadeh et al. concerning the minimum number of probes required to reconstruct the entire ordering of a given clone library with high probability. We also examine the related problem of determining the least number of probes required to construct a "tiling" for the library. We give a fairly precise characterization for this number.

The probability of unique solutions of sequencing by hybridization.

We determine the asymptotic limiting probability as m-->infinity that a random string of length m over some alphabet sigma can be determined uniquely by its substrings of length l. This is an abstraction of a problem faced when trying to sequence DNA clones by SBH.
