Preface
This volume contains the papers presented at the Eleventh Latin American Workshop
on Logic/Languages, Algorithms and New Methods of Reasoning 2018 (LANMR 2018).
We include general topics related to Computer Sciences, LA part of LANMR stands both
for “Languages/Logic + Algorithms”, as well as for "Latin America". LANMR 2018 was
held at the Benemérita Universidad Autónoma de Puebla, Puebla, Mexico, on
November 15th, 2018.

This issue honoring the memory of colleague and friend José Ramón Enrique Arrazola
Ramirez, Professor of mathematics at the Benemérita Universidad Autónoma de
Puebla, died October 26, 2018. We recognize his remarkable career and essential
contributions to the research of logic and modeling. LANMR will miss him.
The Eleventh edition of the workshop was organized by the Benemérita Universidad
Autónoma de Puebla, the Universidad de las Américas -Puebla, and the Universidad
Autónoma del Estado de México.

The workshop aimed to bring together active researchers in formal areas of
Computer Science such as Logic, Formal languages, Algorithms, and Non-
Monotonic Reasoning. In Latin America, there are several research groups
interested in these areas. The number of papers and workshops submitted to
different congresses related to Computer Sciences such as IBERAMIA, ENC,
and MICAI provides evidence of such interest. So, LANMR workshop is
designed to promote cooperation among practitioners and researchers across
disciplines who are interested in the formal areas of Computer Sciences.

The aims of the workshop were: to present innovative theoretical work and
original applications of the formal areas of Computer Sciences, to exchange
ideas and to facilitate interaction between researchers of the formal areas of
Computer Sciences, to discuss significant recent achievements in the theory
and automation based on the formal areas of Computer Sciences, to present
critical short and long-term goals for the formal areas of Computer Sciences,
to provide a forum for students to present their current research in the formal
areas of Computer Sciences, and receive feedback from other students and
researchers.

We want to thank all authors who submitted papers as well as all the referees
for their expertise and the time they put into carefully reviewing the papers.

This year the invited speaker is José Antonio Hernández-Servín, Professor of
the Universidad Autónoma del Estado de México. He will provide means to
explore ways in which his research may contribute to the identification and
addressing of problems of common interest in the formal areas of Computer
Sciences.

We also thank the Benemérita Universidad Autónoma de Puebla, and the
Universidad Autónoma del Estado de México for their support. We much
appreciate the Local Committee and staff for hosting and supporting the
Workshop. We are also grateful to the EasyChair team for their support.
