ABSTRACT:
A combinatorial weighing or counting method and apparatus in which a plurality of articles are weighed to provide a plurality of weight values, or to provide a plurality of discrete numbers found from the weight values, the weight values or numbers are combined, and the optimum combination thereof is found whose sum is equal or closest to a set target value. In the inventive weighing method and apparatus, (1) the purality of weight values are divided into a plurality of groups, (2) there are computed summed weight values for each group by adding the weight values in each and every combination of weight values that constitute the group, (3) every combination of the summed weight values in which single summed weight value is permitted to be selected from each group, is searched, (4) the difference is computed between the set target value and a total weight value obtained by adding the summed weight values in each and every combination of the summed weight values, and (5) the combination of summed weight values whose sum gives the smallest difference is regarded as the optimum combination.
