Center node: "the size change termination principle for constructor based languages"
  Abstract: This paper describes an automatic termination checker for a generic#N#first-order call-by-value language in ML style. We use the fact that value are#N#built from variants and tuples to keep some information about how arguments of#N#recursive call evolve during evaluation. The result is a criterion for#N#termination extending the size-change termination principle of Lee, Jones and#N#Ben-Amram that can detect size changes inside subvalues of arguments. Moreover#N#the corresponding algorithm is easy to implement, making it a good candidate#N#for experimentation.
