<br>
the default value is -1*HUGE(), which essentially means that the 
optimization will never stop because of E_TARGET. This keyword is only 
useful when you (roughly) know the minimum energy of your system.<br>
<br>
Note that the global optimization algorithms in CP2K are a bit dated. You might want to have a look at ASE instead: <a href="https://wiki.fysik.dtu.dk/ase/tutorials/tutorials.html#global-optimization" target="_blank" rel="nofollow" data-saferedirecturl="https://www.google.com/url?hl=en&q=https://wiki.fysik.dtu.dk/ase/tutorials/tutorials.html%23global-optimization&source=gmail&ust=1611495579803000&usg=AFQjCNF3q2xOLn-EZdZou6P26ygeb_11vA">https://wiki.fysik.dtu.dk/ase/tutorials/tutorials.html#global-optimization</a><br>
