[algogeeks] Ternary Huffman Algorithm
Hi all, Pls help me with the following problem.. Generalize Huffman s algorithm to ternary codewords(i.e codewords using the symbols 0,1,2) and prove tht it yeilds optimal ternary codes Thanks in advance -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

its same. instead of taking min 2, select mnimum 3. but since the no.of symbols may not form complete 3-ary tree, so add some dummy variable with value=0 (highest priority). extend this logic for n symbols.

[algogeeks] Re: binary matrix
For square matrix , link suggested by Amit would work. Finding a sub- rectangle is tougher. I would go this way; First scan from bottom right till top left and for every Non-zero member in matrix create this pair ( width , depth ). Width is how many continuous 1's ( including itself ) are there to its right, Depth is how many continuous 1's ( including itself ) are there down wards now select a point P(i,j) , which has value Pair ( W , D ) it means W-1 columns to right and D-1 rows below are '1' , Note: it doesn't give any info about diagonal entries to P , and we will see , we actually don't need them. Now think about all possible rectangles which could be made when P is left top corner so go columnwise from i to i + 1 , i +2 , i + (W-1) points ( call it P' point ) , at every step, see the minimum depth for all points between P and P' and keep calculating area by width X minDepth e.g. P has width = 3, depth = 4 and co-ordinates (i,j ) then go like this Area for A[i,j] and P'[i, j+1 ] = 2 X MinDepth( P, P') //A1 Area for A[i,j] and P[i, j+2 ] = 3 X MinDepth( P, P', P) //A2 : Note MinDepth is Minimum Depth of all three points so far Take Max of A1,A2 and you would have max rectangle which could be created by having P as top left corner. Now , keep traveling P throughout this Matrix. There are few optimisation. A point with width W and depth D can AT MAX has a rectangle with AREA MAX = W * D so next time consider points only whose W * D Max Area calcuated so far.E.g if you have already got a point which has sub rectangle with area = 12 no need to look for points which has such (W,D) pairs = ( 2,3) , (4,2) , (3,3) etc . Time complextiy : First time reverse traversal O(m * n ) /// m Rows , n Columns Second time , MAX AREA calculation for each points , worse case o(n) as we need to travel only column wise as explained above Above action to be done for m*n points so total O( mn * n ) = O(mn^2) So total Time = O ( m * n^2 ) Time complexity :O ( 2 * m * n ) as W and D pair for each entry has to be maintained Suggestions, Clarifications, Modifications ? -Manish -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
