[galib] Help: still about initializer?

[yi.zong@risoe.dk]

Dear all,

   Thank you for your help for my  question.

   I write my initializer. But the first generation's individuals are always zeros and they are not the real number, Like 19.2.

   Could you tell me why?

   Please, see my code snippet from my application as follows. 

   Looking forward to your answer.

main(int argc, char** argv)

{

 

/*

// See if we've been given a seed to use (for testing purposes).  When you

// specify a random seed, the evolution will be exactly the same each time

// you use that seed number.

 

  for(int jj=1; jj<argc; jj++) {

    if(strcmp(argv[jj++],"seed") == 0) {

      GARandomSeed((unsigned int)atoi(argv[jj]));

    }

  }*/
