Design and Analysis of Algorithm. Thus we need only consider points whose x-coordinate satisfies c- < x < c+ Thus we may reduce the set of points to be considered to those lying in the open vertical strip of width 2 centered at L, Closest Pairs Algorithm • Second observation: If we consider the points in the strip in order of non-decreasing y-coordinate, we need only compare each point with points above it Moreover, when checking point p, we need only consider points whose y-coordinate is less than  more than that of p. This means that we only consider points in the rectangle with width 2 and height  centered on the line L and having p on its lower edge, Closest Pairs Algorithm • Third observation: There are at most 7 other points in the rectangle for p Break the rectangle up into /2 by /2 squares: The distance between two points in /2 by /2 square is ≤ Since each square is contained in the left or the right set, it can containat most one of the points in P, Running Time • If we consider the points in the strip in non-decreasing order of their y-coordinates, we need only compare each point to at most 7 other points • Thus the cost of finding the smallest distance between pairs of points in the strip is at most 7n • This gives the following recurrence for the running time: T(n) = T(n/2 ) + T(n/2 ) + 7n • By the Master Theorem, we then have T(n) = (nlg n), Closest Pair Algorithm closest_pair(p) { n = p.last mergesort(p,1,n) // sort by x-coordinate return recursive_closest_pair(p,1,n) } // recursive_closest_pair assumes that the input is sorted by x-coordinate // At termination, the input is stably sorted by y-coordinate, Closest Pair Algorithm recursive_closest_pair(p,i,j) { if (j-i < 3) { mergesort(p,i,j) // sort by y-coordinate // Find a closest pair directly delta = dist(p[i],p[i+1]) if (j-i = 1) // two pointsreturn delta if (dist(p[i+1],p[i+2] ) < delta) delta = dist(p[i+1],p[i+2]) if (dist(p[i],p[i+2] ) < delta) delta = dist(p[i],p[i+2]) return delta }, Closest Pair Algorithm // recursive_closest_pair(p,i,j) continued k = (i+j)/2l = p[k].x deltaL = recursive_closest_pair(p,i,k)deltaR = recursive_closest_pair(p,k+1,j)delta = min ( deltaL, deltaR ) // p[i..k] and p[k+1..j] are now sorted by y-coordinatemerge(p,i,k,j) // p[i.. j] is now sorted by y-coordinate // Next store the points in the vertical strip in another array// On next slide, Closest Pair Algorithm // recursive_closest_pair(p,i,j) continued // next, store the points in the vertical strip in another array t = 0 // index in the vertical strip array vfor m = i to j if ( p[m].x > l-delta && p[m].x < l +delta ) { t = t+1 v[t] = p[k] } for m = 1 to t-1 for s = m+1 to min(t,m+7) delta = min( delta, dist(v[m],v[s] ) return delta }, © 2020 SlideServe | Powered By DigitalOfficePro, - - - - - - - - - - - - - - - - - - - - - - - - - - - E N D - - - - - - - - - - - - - - - - - - - - - - - - - - -.
