Although it becomes possible to write programs in Malbolge language due to the development of the low-level assembly language, the programming in the low-level assembly language is difficult. This is because the arithmetic instructions of the low-level assembly language are not those of ordinary programming languages, but the same as the ones of Malbolge. To construct a program in low-level assembly language, it is necessary to find instruction sequences of Malbolge that implement binary trit-wise functions. For finding such instruction sequences, however, an inefficient exhaustive search is the only known method, which is one of limitations in developing programs in the low-level assembly language. In this paper, to solve this problem, we propose a method to find instruction sequences of Malbolge that implement binary trit-wise functions, which is more efficient due to the use of state-of-art SAT solvers. We formalize a problem that finds an instruction sequence of Malbolge that implements a given binary trit-wise function, and propose a SAT encoding for this problem. Experiments shows that our method is able to find instruction sequences faster than the existing method and hence essentially longer ones.", "subitem_description_language": "en",
