    About FLOPS

    Writing down detailed computational steps is not the only way of programming. The alternative, being used increasingly in practice, is to start by writing down the desired properties of the result. The computational steps are then (semi-)automatically derived from these higher-level specifications. Examples of this declarative style include functional and logic programming, program transformation and re-writing, and extracting programs from proofs of their correctness.

    FLOPS aims to bring together practitioners, researchers and implementors of the declarative programming, to discuss mutually interesting results and common problems: theoretical advances, their implementations in language systems and tools, and applications of these systems in practice. The scope includes all aspects of the design, semantics, theory, applications, implementations, and teaching of declarative programming. FLOPS specifically aims to promote cross-fertilization between theory and practice and among different styles of declarative programming.

    Previous FLOPS meetings were held at Fuji Susono (1995), Shonan Village (1996), Kyoto (1998), Tsukuba (1999), Tokyo (2001), Aizu (2002), Nara (2004), Fuji Susono (2006), Ise (2008), Sendai (2010), Kobe (2012), Kanazawa (2014), and Kochi (2016).


    FLOPS solicits original papers in all areas of the declarative programming:

    FLOPS promotes cross-fertilization among different styles of declarative programming. Therefore, submissions must be written to be understandable by the wide audience of declarative programmers and researchers. Submission of system descriptions and declarative pearls are especially encouraged.

    Submissions should fall into one of the following categories:

    System descriptions and declarative pearls must be explicitly marked as such in the title.

    Submissions must be unpublished and not submitted for publication elsewhere. Work that already appeared in unpublished or informally published workshops proceedings may be submitted. See also ACM SIGPLAN Republication Policy.


    The proceedings will be published by Springer International Publishing in the Lecture Notes in Computer Science (LNCS) series, as a printed volume as well as online in the digital library SpringerLink.

    Post-proceedings: The authors of 4-7 best papers will be invited to submit the extended version of their FLOPS paper to a special issue of the journal Science of Computer Programming (SCP).

    Final Call for Paper (Text)

    Submissions must be written in English and can be up to 15 pages long including references, though pearls are typically shorter. The formatting has to conform to Springer's guidelines. Regular research papers should be supported by proofs and/or experimental results. In case of lack of space, this supporting information should be made accessible otherwise (e.g., a link to a Web page, or an appendix).

    Papers should be submitted electronically at:
