Their construction follows a uniform recipe: build the minimal dfa for L in a locally finite variety V , and apply an equivalence between the finite V -algebras and a category of finite structured sets and relations. By instantiating this to different varieties we recover three well-studied canonical nfas (the átomaton, the jiromaton and the minimal xor automaton) and obtain a new canonical nfa called the distromaton. We prove that each of these nfas is minimal relative to a suitable measure, and give conditions for state-minimality. Our approach is coalgebraic, exhibiting additional structure and universal properties. %G English %Z TC 1 %Z WG 1.3 %2 https://inria.hal.science/hal-01408760/document %2 https://inria.hal.science/hal-01408760/file/328263_1_En_11_Chapter.pdf %L hal-01408760 %U https://inria.hal.science/hal-01408760 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC1 %~ IFIP-LNCS-8446 %~ IFIP-WG1-3 %~ IFIP-CMCS
