How to bulk-load an r-tree in C#? -


i looking c# code construct r-tree. have code builds r-tree incrementally i.e. items added 1 one tree, guess better r-tree built if items given @ once tree creation algorithm. please let me know if knows how bulk-load r-tree in manner. tried doing search couldn't find useful.

the common method low-dimensional point data sort-tile-recursive (str). that: sort data, tile optimal number of slices, recurse if necessary.

the leaf level of str-loaded tree point data have no overlap, good. higher levels may have overlap, str not take extend of objects account.

a proven bulk-loading key component priority-r-tree, too.

and when not bulk-loading, insertion strategy makes big difference. r-trees built linear splits such guttmans or ang-tan worse built r*-tree split heuristics. in particular ang-tan tends produce "sliced" pages, unbalanced in spatial extend. fast split strategy , simplest, results aren't good.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
