Also the measures printed (Coverage, Total number of goals, fitness, statements, nr of generations) differ. In the command, I include -seed  and  -Drandom_seed  arguments.\nI attach one example  (classes, command and output from two executions)  taken from Defects4J for ease the reproducibility of this issue. I generated the jar from commit \n608a41147e224af6889ba4c70b79f94dbbcc498f (not included in the attachment). I executed the same command two times and the output are different.\n\nThanks for you help\nBest regards\nMatias\n\n[exampleRandom.zip](https://github.com/EvoSuite/evosuite/files/384306/exampleRandom.zip)\n"},"comment":{"url":"https://api.github.com/repos/EvoSuite/evosuite/issues/comments/267566149","html_url":"https://github.com/EvoSuite/evosuite/issues/48#issuecomment-267566149","issue_url":"https://api.github.com/repos/EvoSuite/evosuite/issues/48","id":267566149,"user":{"login":"monperrus","id":803666,"avatar_url":"https://avatars.githubusercontent.com/u/803666?v=3","gravatar_id":"","url":"https://api.github.com/users/monperrus","html_url":"https://github.com/monperrus","followers_url":"https://api.github.com/users/monperrus/followers","following_url":"https://api.github.com/users/monperrus/following{/other_user}","gists_url":"https://api.github.com/users/monperrus/gists{/gist_id}","starred_url":"https://api.github.com/users/monperrus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/monperrus/subscriptions","organizations_url":"https://api.github.com/users/monperrus/orgs","repos_url":"https://api.github.com/users/monperrus/repos","events_url":"https://api.github.com/users/monperrus/events{/privacy}","received_events_url":"https://api.github.com/users/monperrus/received_events","type":"User","site_admin":false},"created_at":"2016-12-16T10:39:21Z","updated_at":"2016-12-16T10:39:21Z","body":"Thanks Gordon.\r\n\r\n> why is it important to get deterministic results?\r\n\r\n- debugging\r\n- reproducible automated experiments for the sake of open-science."}}
