i'm trying write c program prints grid each year. have loop iterates prints grid each year how many years choose in argument. loop prints grid endless number of years exceeding boundary put on reason. here's code: int main(int argc, char *argv[]) { if (argc != 3) /* argc should 2 correct execution */ { /* print argv[0] assuming program name */ printf("usage: %s filename", argv[0]); } else { int year = atoi(argv[1]); double grida[11][11]; double gridb[11][11]; int in; int n; printf("%d\n",year); file *file = fopen(argv[2], "r"); (int = 0; < 12; i++) { fscanf(file, "%lf %lf %lf %lf %lf %lf %lf %lf %lf %lf %lf %lf", &grida[i][0], &grida[i][1], &grida[i][2], &grida[i][3], &grida[i][4], &grida[i][5], &grida[i][6], &grida[i][7], &grida[i][8], &grida[i][9], &grida[i][10], &grida[i][11]); ...

just noticed benchmarks, slow query result z3 via java api. however, if dumped query smt2 format, , run z3 in command line directly, takes less second. wonder why? i noticed problem contains (push) command, removing changes performance dramatically. when z3 first sees (push) , switches different solver supports incrementality , can have dramatic impact on performance. setting verbosity 15 via -v:15, first line of z3s output tells solver using, e.g., when push command present says (combined-solver "using solver 2 (without timeout)") and when not, says (combined-solver "using solver 1") for given example, solver 2 happens faster.

tl;dr: should use sql join table or redis sets store large amounts of many-to-many relationships i have in-memory object graph structure have "many-to-many" index represented bidirectional mapping between ordered sets: group_by_user | user_by_group --------------+--------------- louis: [1,2] | 1: [louis] john: [2,3] | 2: [john, louis] | 3: [john] the basic operations need able perform atomic "insert at" , "delete" operations on individual sets. need able efficient key lookup (e.g. lookup groups user member of, or lookup users members of 1 group). looking @ 70/30 read/write use case. my question is: best bet persisting kind of data structure? should looking @ building own optimized on-disk storage system? otherwise, there particular database excel @ storing kind of structure? before read further: stop being afraid of joins . classic case using genuine relational database such postgres. there few reasons this: ...
