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 ...

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...
