This book constitutes the thoroughly refereed post-conference proceedings of the 11th International Symposium on Trends in Functional Programming, TFP 2010, held in Norman, OK, USA, in May 2010. The 13 revised full papers presented were carefully reviewed and selected from 26 submissions during two rounds of reviewing and improvement. The papers cover new ideas for refactoring, managing source-code complexity, functional language implementation, graphical languages, applications of functional programming in pure mathematics, type theory, multitasking and parallel processing, distributed systems, scientific modeling, domain specific languages, hardware design, education, and testing.

This volume presents eight carefully revised texts of selected lectures given by leading researchers of the field at the first Central European Functional Programming School, CEFP 2005, held in Budapest, Hungary, in July 2005. The eight revised full papers presented were carefully selected during two rounds of reviewing and improvement for inclusion in the book. The lectures cover a wide range of topics such as new programming language concepts for subtyping.

This volume presents the revised lecture notes of selected talks given at the Fifth Central European Functional Programming School, CEFP 2013, held in July 2013 in Cluj-Napoca, Romania. The 14 revised full papers presented were carefully reviewed and selected. The lectures cover a wide range of distributed and multicore functional programming subjects. The last 5 papers are selected papers of the PhD Workshop organized for the participants of the summer school.

This volume presents the revised lecture notes of selected talks given at the Fourth Central European Functional Programming School, CEFP 2011, held in June 2011 in Budapest, Hungary. The 11 revised full papers presented were carefully reviewed by experts on functional programming and revised based on the reviews. The lectures cover a wide range of distributed and multicore functional programming subjects. The last 2 papers are selected papers of the PhD Workshop organized for the participants of the summer school.

This volume presents the revised lecture notes of selected talks given at the 6th Central European Functional Programming School, CEFP 2015, held in July 2015, in Budapest, Hungary. The 10 revised full papers presented were carefully reviewed and selected. The lectures covered a wide range of functional programming and C++ programming subjects.
