the problem states want show independent set poly-time reduces relative prime sets, more formally independent set <p relative prime sets . i need provide reduction f ind.set rel. prime sets, where - input of f must graph g , integer k, k denotes size of independent set. - output of f must set s of integers , integer t, t denotes number of pairwise relative prime numbers in set s. definition of relative prime sets (decision version): it takes set p of n-integers , integer t 1 n. returns yes if there's subset of p, t-many pairwise relative primes. is, a, b in a, must true gcd(a, b) = 1. returns no otherwise so far have come-up believe reduction, not sure if valid , want double check knows how this. reduction: let g graph.let k indicate size of independent set. want find-out if there exists independent set of size k in g. since problem np-complete, if can solve np-complete problem in poly-time, know can solve independent set in...

i have 1 relative layout, inside added 3 image button dynamically. when layout first appear 3 button action click event working properly, rotate whole layout per sensor changed, after rotation of layout button's postion changed can't click event of buttons again @ new postion instead got click event on button's previous positions. please suggest me proper solution. any appreciated. below code how added button , apply roation it's parent view. imagebutton mimage = new imagebutton(context); mimage.setx(x); mimage.sety(x); mimage.setid(id); mimage.settag(id); mimage.setimageresource(r.drawable.dot); this.addview(mimage); rotation code, rotateanimation ra = new rotateanimation(currentdegree, -degree, animation.relative_to_self, 0.5f, animation.relative_to_self, 0.5f); ra.setduration(210); ra.setfillafter(false); view.startanimation(ra);

i'm working on open source sock_dgram used send rtp packets. like this: int sock = socket(af, sock_dgram, 0); but i'm supposed use same socket sock_raw send udp packets prepare. is possible convert udp socket raw socket? if possible how can done? thanks in advance i don't know why said need use same socket , otherwise, can follow below steps transfer packet on raw socket. create socket using sock_raw . define , populate ip header [ struct ipheader ] define , populate udp header [ struct udphdr ] set socket not use system (kernel) provied header [ setsockopt() ip_hdrincl as 1 ] send buffer [ sendto() ] you can find nice tutorials (and maybe sample codes, too) here .
