<br><font size=2 face="sans-serif">It would be very tricky to decide what
should be kept round loadProblem - e.g. should minimization be kept. If
nothing is kept then it should be a constructor. </font>
<br>
<br><font size=2 face="sans-serif">As you say the one clean solution is
to have a base empty model which has settings you want to keep e.g. minimization
and then clone from that.</font>
<br>
<br><font size=2 face="sans-serif">However this may not always be best
solution. Laci suggested that we add a "reset" function
to interfaces which would set back as if default constructor. It
would not involve any more coding as the current default constructor coding
would be copied to reset() and the default constructor just call reset.</font>
