<span>Hi Aditya,</span><br>
<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">https://wiki.fysik.dtu.dk/ase/tutorials/tutorials.html#global-optimization</a><br>
<br>
<span>Cheers,</span><br><div>
