Overview of terms. Sequences, patterns, and solutions can be segregated to their elemental parts. The sliding window is part of the sequence that is to be searched. This size is defined by the maximal size of the total pattern. The total pattern is segregated into subpatterns that are suited for computation in the 3of5 algorithm. Matching subpatterns become a subsolution. Every branch of a solution tree becomes a total solution, once also the final subpattern has matched.
