artificial-intelligence

I have Xcode 4.6. I downloaded this project When run it i receive a message No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=armv7 armv7s). Where and what i have to change? I have no idea what should i do? Thanx If you are in Xcode 5.0 , this may arise if you select a 64 bit (simulator for iPhone 5S) simulator instead of 32 bit simulator. This happened to me. It may help some one, because I didn't find any answer to solve this till I found it myself. Go to Project Target > Build Settings > Architectures and make Build Active Architecture Only = NO The

I am looking for a solution to 8-puzzle problem using the A* Algorithm . I found this project on the internet. Please see the files - proj1 and EightPuzzle . The proj1 contains the entry point for the program(the main() function) and EightPuzzle describes a particular state of the puzzle. Each state is an object of the 8-puzzle. I feel that there is nothing wrong in the logic. But it loops forever for these two inputs that I have tried : {8,2,7,5,1,6,3,0,4} and {3,1,6,8,4,5,7,2,0} . Both of them are valid input states. What is wrong with the code? Note For better viewing copy the code in a

My current project is to build a face authentication system. The constraint I have is: during enrollment, the user gives single image for training. However, I can add and use images given by the user while authentication. The reason I want to add more images into training is, the user environment is not restricted - different lighting conditions, different distance from camera, from different MP cameras. The only relief is the pose is almost frontal. I think, the above problem is similar to the face tagging app widely available. Can anyone suggest a method to use the available images

I'm making a small project where i have to detect points scored from a given image of paper target. Something similar to TargetScan app for iPhone. I'm using openCV for processing image and basically i have two parts for this, one is to detect circles from a target(which works pretty good with Hough Circle Transform) and the second part is to detect shots. I need some ideas how to detect those shots from a given image. Here is an example image with circle detection ON (green line for circles detected and red point for center). What algorithms from openCV can be used to detect those shoots?

I need code for the ranking selection method on a genetic algorithm. I have create roulette and tournament selections method but now I need ranking and I am stuck. My roulette code is here (I am using atom struct for genetic atoms) : const int roulette (const atom *f) { int i; double sum, sumrnd; sum = 0; for (i = 0; i < N; i++) sum += f[i].fitness + OFFSET; sumrnd = rnd () * sum; sum = 0; for (i = 0; i < N; i++) { sum += f[i].fitness + OFFSET; if (sum > sumrnd) break; } return i; } Where atom : typedef struct atom { int geno[VARS]; double pheno[VARS]; double fitness; } atom; Rank selection is
