Generating All Forest Extensions of a Partially Ordered Setally ordered set is a . when the set of ancestors of any given element forms a chain. We describe an algorithm for generating the complete set of forest extensions of an order .. The algorithm requires .(..) time between the generation of two consecutive forests. The initialization of the algorithm requires .(.|.|) time.

On the Generation of Extensions of a Partially Ordered Set transitivity. The set . is called the ground set of ., while . is the relation set of it. There are many special orders. For example, when any two elements of . are related, the order is a chain. Similarly, we can define tree orders, forest orders and many others. An extension .′ of . is an order .
