android - Dependency between method Settings.canDrawOverlays and Permission Settings -


is there dependency between method settings.candrawoverlays , permission settings?

  1. i manually set possibility draw overlays on;
  2. logs show settings.candrawoverlays(this) returns true;
  3. when click on apps->myapp->permissions (nothing else) , settings.candrawoverlays(this) begins return false;
  4. if press "back" settings.candrawoverlays(this) again returns true.

is normal behavior of system?

javascript - Training Neural Network to play flappy bird with genetic algorithm - Why can't it learn? -

Image
i have been learning neural networks , genetic algorithms, , test learning, have tried make ai learns play flappy bird: i have left running @ least 10 hours (overnight , longer), fittest member still fails show significant advancements in intelligence when began simulation apart avoiding floor , ceilings. inputs rays (as can see above) act sight lines, , network fed in lengths, , birds vertical velocity. seems best bird ignoring sight lines except horizontal one, , when short, jumping. output number between 0 , 1, if output larger 0.5, bird jumps. there 4 hidden layers, 15 neurons each, input layer feeding forward first hidden layers, 1st hidden layer feeding forward 2nd 1 ... , final hidden layer feeding forward output, dna of bird array of real numbers representing weights of neural networks, have made project using same style of neural network, , genetic algorithm, in ants had travel food, , worked perfectly. here code: https://github.com/karan0110/flappy-bird-ai please ...
