A motion estimation algorithm finds the best match for a given block or macroblock so that the resulting error signal has very low energy level which is computed, for e. A selected one of a pair of fame brackets or hangers for pivotally mounting suspension assemblies of an axlesuspension system, includes vertically-oriented oval sidewall openings and vertically-spaced horizontally extending eccentric collar guide tabs. For this, the method comprises computing a first rewriting rule and a second rewriting rule corresponding respectively to a transformation of an initial graph into the first graph and the second graph, determining a third rewriting rule by assembling the first rewriting rule and the second rewriting rule, and computing a merged graph by applying the third rewriting rule to the initial graph. Players may select or adopt and modify a particular character for bonus game play, and team play between teams of players may also be offered.
