Efficient Exact and Approximate Algorithms for the Complement of Maximal Strip Recovery
Given two genomic maps G and H represented by a sequence of n gene markers, a strip (syntenic block) is a sequence of distinct markers of length at least two which appear as subseq...

Combining integer programming and the randomization method to schedule employees
: We describe a method to find low cost shift schedules with a time-varying service level that is always above a specified minimum. Most previous approaches used a two-step procedu...
