for a* search algorithm, provided heuristic h, supose h admisible. that is: h(n) ≤ h*(n) every node n, h* real cost n goal . does ensure heuristic monotone? that is: f(n) ≤ g(n') + h(n') every sucesor n' of n, f(n)= h(n) + g(n) , g(n) accumulated cost. no. assume have 3 successor states s1 , s2 , s3 , goal state g s1 -> s2 -> s3 -> g . s1 starting node. consider following values h(s) , h*(s) (i.e. true cost): h(s1) = 3 , h*(s1) = 6 h(s2) = 4 , h*(s2) = 5 h(s3) = 3 , h*(s3) = 3 h(g) = 0 , h*(g) = 0 following path goal can have that: g(s1) = 0, g(s2) = 1, g(s3) = 3, g(g) = 6 , coinciding true cost above. although heuristic function admissible ( h(s) <= h*(s) ), f(n) not monotonic. instance f(s1) = h(s1) + g(s1) = 3 while f(s2) = h(s2) + g(s2) = 5 f(s1) < f(s2) . same holds between f(s2) , f(s3) . of course means have quite uninformative heuristic.

every n seconds application requesting remote json file provides live prices securities in trading system. json has block data need ( marketdata ) , block current dataversion ( version , seqnum ). right use actioncontroller::live (with eventsource on client side) push updated data browser. actions done within 1 method: opening sse connection; forming dynamic url; pulling new data remote server; comparing/reassigning seqnum value; updating database if needed. so goal separate pulling & updating database ( activejob ) pushing updated values browser ( actioncontroller::live ). accomplish need: either store somewhere on server side seqnum & version share between controller , background job; or monitor databases latest changes in updated_at fields. so have 2 questions: what more efficient between 2 options above?are there other approaches?

i using r, , need recode variables in list. list follows: > list1 group.1 x 1 4000 2 3890 where in group.1 column replace instance of 1 male , , 2 female . i have tried replace() function: replace(list1,list1$group.1 == "1", "male") which returns group.1 x male 4000 male 3890 i.e., has relplaced group.1 == 2 male. have missed step? far can see use of replace function - group.1 == 1 should limit replace command values in group.1 equal 1. seems criteria not doing anything. replace operates on vectors, not data.frames. try this: > replace(df$group.1,df$group.1 == 1, "male") [1] "male" "2" and change data, can do: > df$group.1 <- replace(df$group.1,df$group.1 == 1, "male") > df group.1 x 1 male 4000 2 2 3890 what trying looks application factor column levels c("male", "female") .

so, have array containing integers. need sort it. however, operation can perform unit shift. is, can move last element of sequence beginning. `a1, a2, ..., an → an, a1, a2, ..., an - 1.` what minimum number of operations need sort sequence? the number of integers in array can upto 10^5. , each integer individual value can 10^5 too. also, if array sorted, print 0 else if array cannot sorted unit shifts, print -1. the solution thought of: check if array sorted or not. if array sorted, print 0 else set count = 0 rotate array 1 unit , increment count. check if array sorted: if yes, print count , break, else repeat steps 4-5 till count < (total integers in array). now, above solution has time complexity of o(n^2). because, checking each individual element if array sorted , checking takes o(n) time, , have n elements, makes o(n^2). can suggest me other better approach? thanks! ps: tried hard thinking of other approach. reached uptill counting inversion...

i have table users data password column encoded using encrypt library in codeigniter. now, want select encoded column decode , compare password's user input (login validation). here's code. inserted value this: $this->db->insert("my_table",array("username"=>$this->input->post("username"),"password"=>$this->encrypt->encode($this->input->post("password")))); for validate input way: $data = $this->db->get("mytable"); foreach($data $d){ if($d["username"] == $this->input->post("username") && $d["password"] == $this->encrypt->decode($this->input->post("password")){ //success break; } } this works fine me but, want shorter , cleaner way this. know, also, future coding practice. here's have done far: $this->db->get_where("my_table",array($this->encrypt->decode(...

https://stackoverflow.com/a/28334583/4107801 i tried method mentioned in answer crashes bad access every time. maybe private apis have changed or i'm implementing incorrectly. here implementation: override func loadview() { view.frame = cgrect(origin: cgpoint(x: 100, y: 100), size: cgsize(width: 1000, height: 1000)) //view = self.view splitview = nssplitview(frame: view.frame) splitview?.autoresizingmask = .viewwidthsizable | .viewheightsizable splitview?.setposition(300, ofdivideratindex: 0) view.addsubview(splitview!) } loadview doesn't init contentview in controller have manually too. adding view = nsview(frame:cgrect(origin: cgpoint(x: 100, y: 100), size: cgsize(width: 1000, height: 1000))) solved problem.

using polymer-starter-kit-1.0 (to going more quickly) trying establish data-binding against plain javascript objects (instead of other polymer custom-elements). this seems initial value of property binding to. for simplicity: added "test" object name property main app object, app.test = { 'name': 'john doe' } and added element on home page this: <h3>app name: <span>[[test.name]]</span></h3> this display initial value ('john doe'). when change name of javascript object javascript code directly, (on-click event of button) in app.test.name = 'jim smith' nothing changes in one-way bindings. however, if add input element this: <input value="{{test.name::input}}" /> then span element updated when text changed in input element. it if changes made directly javascript not observed polymer. what doing wrong? it looks may have not used bindings property properly. doesn...

i have set of non-orthogonal policies, of them implementing common named method, policies add safety checks. want users able combine policies allow more complex validation without creating policies each combination case hand. approach creating new policy class combine others. the simplified example below shows c combining class, here method id combined. expected result is, when calling id on c, sequentially call id of each base class. #include <iostream> using namespace std; struct { void id() { cout << "a ";} }; struct b { void id() { cout << "b ";} }; template<class a, class... as> struct c : public a, public as... { void id() { a::id(); as...::id(); // line not work, illustrative. } }; int main() { c<a, b> c; c.id(); //expected: result b } the question is: possible expand as... somehow without using recursive approach, using ... operator? sure. need contex...

i'm trying use laravel access data database. have setup model, works fine, i'm trying fetch data table creating method within model fetches data , sets property of model equal fetched data. to fetch data, i'm trying use $this->id property fetch row's id , use fetch data table (eg: someothermodel::where('other_id', '=', $this->id)->get(); ) however, none of data database seems have been fetched model @ point (eg: $this->id null). constructor looks so: public function __construct() { parent::__construct(); $this->other_data = $this->getotherdata(); } is there way call $this->id property database can use within model itself? your syntax seemed me wrong: someothermodel::where('other_id', '=', $this->id)->get(); can try this: someothermodel::where('other_id', $this->id)->get(); reference: https://laravel.com/docs/5.1/eloquent#retrieving-single-models i hope help...

this question has answer here: why golang handle closures differently in goroutines? 2 answers wrapping function call closure leads unexpected behaviour when using goroutines. consider following example: package main import ( "log" "sync" "time" ) var workernum = 5 var wg sync.waitgroup func block() { dur := 300 * time.millisecond //time.sleep() select { case <- time.after(dur): {} } } func startworker(worker int) { i:=0; < 3; i++{ log.printf("worker %d woke up! \n", worker) block() } wg.done() } func main() { i:=0; < workernum; i++ { //go func() { startworker(i) }() go startworker(i) } wg.add(workernum) wg.wait() } test here: http://play.golang.org/p/nmlntkbwvf one can see wrapping startworker(i) func() { startwo...

i've heard said gwt use closure compiler code pruning. if closure compiler wouldn't prune gwt code that's being used javascript javascript code call gwt code long javascript code given closure compiler? work , if why focus on @jsexport , @jstype? excited js interop seems closure compiler offers potential effortless interop.
