First-fit-decreasing (FFD) is an algorithm for bin packing. Its input is a list of items of different sizes. Its input is a list of items of different sizes. Its output is a packing - a partition of the items into bins of fixed capacity, such that the sum of sizes of items in each bin is at most the capacity.
Box step. The box step is a dance figure named so because the steps rest in the four corners of a square. It is used, e.g., in American Style ballroom dances: rumba, waltz, bronze-level foxtrot. The leader begins with the left foot and proceeds as follows. [2] First half-box: Forward-side-together Second half-box: Backwards-side-together
The steps of a dance or pattern may be listed in a step sheet. Dance patterns may be described by difficulty. [7] Dance patterns may be described according to combinations of quick and slow steps and often by the rhythm or meter of the music, for example waltz steps (three-count step patterns danced to waltz music), swing steps (four-count ...
In ice dancing, chassés are basic dance steps which appear, for example, in many compulsory dances. The International Skating Union rules define the following variants: [ 1 ] Simple chassé: a step in which the free foot is placed on the ice beside the skating foot, which is then lifted close to the new skating foot with the blade parallel to ...
The algorithm can be made much more effective by first sorting the list of items into decreasing order (sometimes known as the first-fit decreasing algorithm), although this still does not guarantee an optimal solution and for longer lists may increase the running time of the algorithm. It is known, however, that there always exists at least ...
The pattern starts with the leader backing DC, e.g., after the first part of the quarter turns: the back lock (SQQS) is performed, followed by the change of the direction on counts SQQ (leader's steps: left foot back (follower steps outside partner), right foot back with a quarter turn to the left, left foot forward facing DW), followed by a slow step outside partner, e.g., into the forward ...

The 6-step. The 6-step is foundational to b-boying not only because it is the first footwork sequence breakers often learn, but also because it remains the move around which many sets are structured. Many break moves can begin from the 6-step. The move sets up the direction of rotation and builds momentum while imparting body control. The ...
