The first international conference organized in Vietnam, which concerns theoretical computer science, was the ICOMIDC Symposium on Mathematics of Computation, held in Ho Chi Minh City in 1988. For the last years great developments have been made in this areas. Therefore, it had become necessary to organize in Vietnam another international conference in this field, which would enable Vietnamese scientists, especially young people, to update the knowledge, to make contacts, to exchange ideas and experiences with leading experts all over the world.
For such a purpose, the conference on Mathematical Foundation of Informatics (MFI99), held at the Institut de Francophonie pour Informatique (IFI) in Hanoi, was co-organized by the Institute of Mathematics and Institute of Information Technology, Vietnam National Center for Natural Sciences and Technologies (now, Vietnam Academy of Science and Technology). This conference was also endorsed as one of the activities of the South East Asian Mathematical Society (SEAMS).
