first of all, want mention homework . however, solve problem can use literature want. even though think problem clear name, give description: "for given undirected graph g , given integer k, g contain totally connected (clique) subgraph of size k or totally disconnected subgraph (independent set) of size k." i know polynomial reductions 3-sat clique , 3-sat independent-set . ( http://mlnotes.com/2013/04/29/npc.html ) however, have problem 1 because cannot combine 2 reductions. tried reduction clique clique-or-independent-set without success. so appreciate hints! thanks in advance. i found out reduction problem independent-set clique-or-independent-set . need add n isolated vertices graph g (which instance of independent-set , has n vertices). let call newly created graph g' (instance of clique-or-independent-set ). not hard prove g has k independent-set iff g' has n+k independent-set of clique (since, construction, cannot have n+k c

so, if i'm checking in enterframe event listener, , want check (if happens) this. somehow checking every frame slow. there way check in infinite speed , not every frame, when checks something, instantly changes position? technically, there no way check faster once per frame, if have frame rate @ 60fps. timer limited trigger @ 60 times per second, , same speed can setting stage.framerate too. but, if checking, example, collision of flies fast , obstacle, before obstacle in current frame, , past next frame, can use derivative of axis-aligned bounding box collision detection, , transition collision detection (a probable example here) , checking if path intersects bounding box in time between 2 frames. if checking process depends on factors , time, , can check condition in frame , previous frame, can interpolate process between frames in conventional enterframe listener , check if condition seeking might happen in between, , if might, might check whether did happen

i have send , receive audio file via websocket using mobile devices. clients android, ios , wp. guys have idea how accomplish this? thought encode file base64 , send string, maybe there better way this? websocket should use? thanks send audio file sequence of binary frames. websocket libraries provide means send , receive binary data. see 5. data framing in rfc 6455 details binary frames.

this question has answer here: why function pointers , data pointers incompatible in c/c++? 14 answers void funcptr(int a); int main(){ int k=1; void (*funcptr2)(int); funcptr2 = (void*)(funcptr); // funcptr2 = (void(*)(int))(funcptr); (*funcptr2)(k); return 0; } void funcptr(int a){ printf("%d", a); } what difference between (void*) , (void(*)(argument type) in function pointer type casting? as result, not occur warning. is wrong? (void*) type casting is wrong? (void*) type casting yes, is. c standard doesn't allow conversion of function pointer object pointer or assignment between them. if compiler warning level, may warnings/errors such compiling with: gcc -wall -wextra -pedantic-errors -std=c11 file.c i not sure why thought casting function pointer. provided function pointer type matches functi

my app using objectify. i'm new nosql . i have data model this. pay no attention lack of getters , setters, lack of builder pattern, etc. example. as can see, reallyweirdcar root of quite deep object graph. now, suppose build reallyweirdcar object in memory using given method. also, assume datastore empty. how save object using objectify ? is ofy().save().entity(rwc1) enough save entire object graph in 1 shot ? how persist relationships ? also, consider "good"(performant) model if of time i'm executing queries "find cars solicited customer john" thx in advance @entity class reallyweirdcar { @id public string id; public string name; @load public ref<engine> e1; @load public ref<engine> e2; // reference customer solicited construction of car @index @load public ref<customer> customer; } @entity class customer { @id public string id;

i cannot understand how cfs:s3 work. on client have images = new fs.store.s3('images') @images = new fs.collection "allimages", stores: [images] filter: allow: contenttypes: ['image/*'] on server same keys. , change event "change .file-image": (e) -> console.log("changed!") fs.utility.eachfile e, (file) -> images.insert file, (err,fileobj) -> console.log 'fileobj',fileobj and after cannot understand do, how upload , url? when create cfs object you'll typically want retain _id , example: let imageid = images.insert file or images.insert file, (err,fileobj) -> let imageid = fileobj._id cfs might take awhile finish loading file , url isn't available until upload finished. let url = fileobj.isuploaded() ? fileobj.url() : null in blaze might like: {{#if this.isuploaded}} <a href="{{this.url}}">download file</a> {{else}}
