algorithm - Job assignment with NO cost, would Hungarian method work? -

so have job assignment problem doesn't have traditional cost hungarian method requires. for example: i have 3 workers - a, b , c have 5 jobs - 1, 2, 3, 4 , 5 each worker has list of jobs can perform, so: worker can work on job 1, 2, 5 worker b can work on job 1, 2 worker c can work on job 1 the end result (since there's no cost) maximum number of assignments can achieve. in example, can achieve maximum of 3 assignments: worker on job 5 worker b on job 2 worker c on job 1 is hungarian method way solve this? should use "dummy" costs? thinking maybe using index of job preference cost; idea? assign cost -1 job can, , others zero. then run hungarian algorithm , give answer(it returns -answer,in fact). don't large numbers, may cause overflow(unless implement hungarian carefully). indeed, it's maximum matchings in bipartite graphs, , there many ways solve problem, see wiki pages: http://en.wikipedia.org/wiki/matching_(graph_theo...

database - Query retrieving vs. calculus - best performance? -

php - Validate string against regex -

i'd validate file paths regular expression. far i've come this: preg_match('/[^a-za-z0-9\.\/\\\\]/', $string); so return 1 if string has other characters a-z, a-z, 0-9, dot, \ , / how can make returns 1 if there more 2 dots in string, or if dot @ end of string? and how can allow : if it's present 2nd character , followed \ or / . example c:\file should valid for first 2 requirements: preg_match('/[^a-za-z0-9\.\/\\\\]|\..*\.|\.$/', $string); the \..*\. match if there more 2 dots. \.$ match if there dot @ end. separating each of these portions (including original regex) | make regex match 1 of expressions (this called alternation). the last requirement little tricky, since if understand correctly need return 1 if there : , unless colon second character , followed \ or / . following regex (as php string) should that: '/:(?!(?<=^[a-za-z]:)[\/\\\\])/' or combined other regex (note have add : first character clas...

subroutine - Perl sub made from string -

i trying use sub in perl contained in string. currently have $sub = "sub{ $in = shift; if($in =~ /bla.*wam/){return 1;}}"; i try , use doing $sub->("test"); or &{$sub}->("test"); both examples above spit out whole function if name of sub not find. looks this: undefined subroutine [function printed here] what getting wrong here? let's scalar $sub contained string "foobar" . if $sub->() , attempting call subroutine named foobar . if subroutine not exist, error. you trying call subroutine name sub{ $in = shift; if($in =~ /bla.*wam/){return 1;}} , thoroughly ridiculous name sub , doesn't exist in program. (and actually, since it's double-quoted, $in interpolated without realizing it.) so, first of all, don't that. if want anonymous subroutine, make this: my $sub = sub { $in = shift; if($in =~ /bla.*wam/) { return 1; } }; then execute this: $sub->("test"); if real...

Two different ways to implement Decorator pattern in PHP -

while doing tutorials on decorator pattern, i've encountered 2 different implementations. implementation 1 (referred i1) implementation 2 (referred i2) in short, i1's parent decorator class implements original object's interface (in example, class propertydecorator implements propertyinterface . original object property implements propertyinterface well). i2's parent decorator class not implement original object's interface (in example, decorator_wrapper not implements cupcake interface. in fact, there not cupcakeinterface @ all). my question is, is merely personal preference of understanding , implementing decorator pattern? or 1 wrong , 1 right? just depends on needs. let's see: abstract class can provide abstract methods. can provide real functions , variables. can extended. class can extend 1 parent. interface can provide abstract methods. a class may implement several interfaces. i prefer using base abstra...

java - Should we ever call setClientId() on the connection factory? -

this in context of creating durable subscription. there setclientid() in defaultmessagelistenercontainer , 1 in singleconnectionfactory . my understanding : durable subscription consumer/subscriber. different consumers should capable of using different client ids. different consumers should able share connection. there 1 (listenercontainer,listener) pair per consumer. so, makes sense setclientid() @ listenercontainer. but, why there setclientid() @ connection factory level ? even though singleconnectionfactory has single connection, connection shared multiple consumers, across multiple sessions. right ? needless more dangerous cachingconnectionfactory (which inherits method singleconnectionfactory). extended version: can 1 should not use setclientid() on single/cachingconnectionfactory ? made more imperative following statement in defaultmessagelistenercontainer's setclientid(): furthermore, client id can assigned if original connectionfactory hasn...

php - Grabbing key value from a mysql query -
