1. A digital information processing system for solving many-valued logic equations comprising:

  • circuitry means for supplying a first plurality of input strings V and a second plurality of groups of input strings C;

    a many-valued logic processor for processing said sequences of many-valued input signals encoded by V strings on the basis of sequences of many-valued input operations encoded by said groups of C strings, and producing sequences of output signals representing U strings, a selected group of said U strings producing a group of binary signals which is the plural-bit code of a many-valued truth value, by carrying out selected many-valued logical operations on said input many-valued truth values (or V strings);

    parallel registers having plural-bit storage locations for storing sequences of input signals representing said second plurality of C strings, sequences of input signals representing said first plurality of V strings, and sequences of output signals representing said output U strings;

    circuitry connecting said many-valued logic processor with said parallel registers plural-bit storage locations for storing sequences of output strings U produced by the many-valued logic processor; and

    ,output processing means for processing a group of selected U strings stored in said parallel registers plural-bit storage locations and producing, for each selected string U, a predetermined binary signal when the bits of said selected string U are all set to a predetermined value.
