Square dance club goal is to promote and advance square dance as a recreational activity. Typically clubs accomplish this goal through the following activities: This is not an exclusive list, and square dance clubs are constantly on the look out for new ways to achieve their goals. Associations, partnerships and other cooperative ventures have become increasingly more important to square dance clubs. Membership in square dance clubs seems to have peaked in the late '70s and early '80s, and has gradually decreased since that time. Providing classes and training opportunities is the main activity for the majority of square dance clubs. This activity
Activity selection problem that |S'| > |S| in the case that multiple maximal solutions have equal sizes. The activity selection problem is notable in that using a greedy algorithm to find a solution will always result in an optimal solution. A pseudocode sketch of the iterative version of the algorithm and a proof of the optimality of its result are included below. Line 1: This algorithm is called "Greedy-Iterative-Activity-Selector", because it is first of all a greedy algorithm, and then it is iterative. There's also a recursive version of this greedy algorithm. Note that these arrays are indexed starting from 1 up to
