β¦ Synopsis
Let sk(n) be the largest integer such that every n-point interval order with NO antichain of more than k points includes an Sk(n)-point 'semiorder. When k = 1, s,(n) = n since all interval ordexs with no two-point antichains are ch:&s.

The recognition complexity of interval orders is shown to be Q(n log, n), and an optimal algorithm is given for the identification of semiorders. \* Supported by the joint research project "Algorithmic Aspects of Combinatorial Optimization" of the Hungarian Academy of Sciences (Magyar Tudomanyos Aka
The generation of combinatorial objects in a Gray code manner means that the difference between successive objects is small, e.g., one element for subsets or one transposition for permutations of a set. The existence of such Gray codes is often equivalent to an appropriately defined graph on these o
