this question has answer here: longest increasing sequence 2d matrix recursion 4 answers assuming have grid: 1 5 7 3 4 9 6 2 8 the solution be: 1-3-4-5-7-9 how solved? i think problem can solved using recursive dp. memoise lenght of longest path obtained starting @ particular point. int dp[rows][cols]={0}; int dfs(int x , int y , int val) { if(dp[i][j] != 0 ) // visited return dp[i][j]; int lengthoflongestpath = 0; search in 4 directions in grid element greater val; // newx, newy,newval lengthoflongestpath = max(lengthoflongestpath , dfs( newx , newy , newval)); lengthoflongestpath ++; // add particular element path dp[x][y] = lengthoflongestpath; return dp[x][y]; } int ans = 0; for(i=0 rows) for(j=0 cols) if(dp[i][j] == 0) // unvisited { dp[i][j] = dfs(i,j,grid[i][j])

my question: why primitive data-types fixed in size? how can collections grow in size dynamically? suppose, primitive data-types contain feature or ability grow in size dynamically. reduce data-types 8 4 " integer " group of integer, float, short, long , float group of float, double. why isn't structure way? any answer full. in advance. hardware primitives have defined size, otherwise you'd have difficulties memory layout, converting bytes primitives , vice versa, etc. software primitives (built-in datatypes provided language) might not need fixed size make memory operations , data transfer more complex operations. as example, if read integer file, how many bytes read? 1,2,4,8? in memory you'd have similar problem: if object consist of 2 short integers, i.e. 2x2 bytes, you'd need move second integer if first needed grow or move entire object. performance penalty wouldn't compensated comfort of having 1 integer type. collection

in radial basis function network (rbf network), prototypes (center vectors of rbf functions) in hidden layer chosen. step can performed in several ways: centers can randomly sampled set of examples. or, can determined using k-mean clustering. one of approaches making intelligent selection of prototypes perform k-mean clustering on our training set , use cluster centers prototypes. know k-mean clustering caracterized simplicity (it fast) not accurate. that why know other approach can more accurate k-mean clustering? any appreciated. several k-means variations exist: k-medians, partitioning around medoids, fuzzy c-means clustering, gaussian mixture models trained expectation-maximization algorithm, k-means++, etc. i use pam (partitioning around medoid) in order more accurate when dataset contain "outliers" (noise value different others values) , don't want centers influenced data. in case of pam center called medoid.
