Monday Night Scoring AlgorithmFor the absurdly curious ...The genuine taken-straight-from-the-program code is shown below, complete with whimsical comments. function float_max(x, y) { // Returns larger number for max float. return (x > y ? x : y); } function sqr(x) { // Returns x**2 return (x * x); } function rand(num) { // Returns a random number between 1 and the number passed in. return Math.floor(Math.random() * num) + 1; } /*************************************************************************** * MondayCurrent(p1, p2, a1, a2): This algorithm is all magic, handed down * * from time immemorial. The idea is basically to award the Monday night * * score based on a standard distance formula, but modified to take * * football stuff into account. In particular, (1) a higher score is * * awarded if you get the point spread right; and (2) the "generosity" * * of the score increases as the actual score of the game gets higher * * under the belief that it's harder to accurately predict a high-scoring * * game than a low-scoring game. * **************************************************************************/ function MondayCurrent(p1, p2, a1, a2) { Half = 21.0; Alpha = 1.6; BAT0 = 3.9; BSlope = 0.048; Points_For_Closeness = 80.0; Bonus_For_Picking_Winner = 20.0; Bonus_For_Picking_Tie = 40.0; b1 = float_max(1.1, BAT0 - BSlope*(a1)); b2 = float_max(1.1, BAT0 - BSlope*(a2)); // Compute distance -- a modified 2-norm. d1sq = sqr(p1-a1); d2sq = sqr(p2-a2); rsq = d1sq + d2sq; dist = Math.sqrt(rsq + (sqr((p1-p2)-(a1-a2)))); // Compute the base -- a weighted average of the bases calculated from // the actual score. if(rsq == 0.0) { s = (a1 == a2 ? 120.0 : 100.0); } else { base = ( (rsq < 0.5) ? 2.0 : ( d1sq*b1 + d2sq*b2 ) / rsq ); s = Math.pow(base, ( - Math.pow((dist/Half), Alpha) )) * Points_For_Closeness; if ( (a1 == a2) && (p1 == p2) ) s = s + Bonus_For_Picking_Tie; if ( ((a1 > a2) && (p1 > p2)) || ((a1 < a2) && (p1 < p2)) ) s = s + Bonus_For_Picking_Winner; } return parseInt(s); } // Used for Median Score calculation function // the actual score. function SortNumeric(a, b) { return ((+a > +b) ? 1 : ((+a < +b) ? -1 : 0)); } function SortVBArray(arrVBArray) { return arrVBArray.toArray().sort(SortNumeric).join('x'); }
