<p class="MsoPlainText"><span lang="EN-US">(since there was no suite of Dana’s request in phenixbb, I suppose that people understood her question and answered her in private; good luck to Dana).<o:p></o:p></span></p>

<p class="MsoPlainText"><span lang="EN-US">It makes me unhappy (saying politely) when, frequently enough, I see/hear the expression "structure minimization" even when it became a part of jargon.<o:p></o:p></span></p>

<p class="MsoPlainText"><span lang="EN-US">Nobody can MINIMIZE a STRUCTURE !<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">One can minimize energy or some other FUNCTION of a model, one can OPTIMIZE a structural model (in the sense that the model fits better some data), but please not “minimize a structure”.

<p class="MsoPlainText"><span lang="EN-US">Such an expression is not really innocent, especially for young researchers, because when talking about minimization (rather optimization) problems, one should have clear in his mind :<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- what is the model, which parameters can be modified (like Dana said, rigid body)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- what is the score function, what will be minimized or maximized (definitely NOT a structure

<p class="MsoPlainText"><span lang="EN-US">- by which minimization method will we achieve this.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">and “structure minimization” makes a confusing of all this.<o:p></o:p></span></p>

<p class="MsoPlainText"><span lang="EN-US">I would wish that we (I mean our community as a whole) “minimize”
