| Title: | Two problems on the generation of linear extensions of posets |
| Author(s)/Inventor(s): | Richa, Andréa Werneck Szwarcfiter, Jayme Luiz |
| Abstract: | Apresentamos dois resultados sobre a geração de extensões lineares de um poset. Primeiro provamos que as extensões lineares de todo poset podem ser geradas por inserção. A seguir, descrevemos um algoritmo de tempo médio constante para gerar as extensões lineares de um poset série-paralelo em ordem lexicográfica. |

Next, we describe a constant average time algorithm to generate the linear extensions of a series-parallel poset in lexicographic order . |
