[TRNSYS-users] negative sign in minimum result of cost function trnopt

[Michel Tamarzians]

Dear all,

When doing an optimization one of the minimum results is positive 2.1E-14
but another minimum result is negative 2.1E-14. Can someone please
elaborate why the results changes to negative while the minimum found is
already much smaller than zero..??

Thank you :)

Kind regards,
Michel
