Zheng et al. introduced a new representation of a genome in terms of a partially ordered set (often abbreviated as “poset”). In this model, any linear extension of a poset represents a possible total order of the genome. In the context of posets, a genome rearrangement problem is to find a linear extension in each poset such that a criterion (number of reversals, number of breakpoints, etc.) is optimized. This chapter focuses on handling rearrangements of gene partial orders.

Keywords:   genome rearrangement, partially ordered sets, posets, linear extension
