formulation 1造句

• In an influential paper, formulation 1 " to machines that still use a two-way infinite binary tape, but whose instructions are simpler  being the " atomic " components of Post's instructions  and are by default executed sequentially ( like a " computer program " ).
• His extremely simple model can emulate any Turing machine, and although his 1936 " Formulation 1 " does not use the word " program " or " machine ", it is effectively a formulation of a very primitive programmable computer and associated programming language, with the boxes acting as an unbounded bitstring memory, and the set of instructions constituting a program.
• Subsequent formalizations were framed as attempts to define " effective calculability " or " effective method "; those formalizations included the recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's " Formulation 1 " of 1936, and Alan Turing's Turing machines of 1936 7 and 1939 . Giving a formal definition of algorithms, corresponding to the intuitive notion, remains a challenging problem.
