Alexander: In a translated pharagraph from spanish to english I say “late but sure”. Sorry about time. I send you this email to give you my brief and humble opinion about the course that you lecture at ECI 2007. I so very happy with the course, ther organization was perfect, Your english was adecuated and easy to understand for the listeners. In my university the course of formal languages is focoused to the construccion of compiler, I we lear the basic theory of formal languages. Im suprised with the result thay you give at the course, focoused in the powerfull of the formal languages and those extension to reconocite the diferent languages. And how a little trick to a known “formalism”, i.e. PDA o Grammars can increase enomoursly the power of them.
Thank you a lot for the Course.
Best Regards.
