To qualify for a final grade it is required that the project assignment is approved as well as passing the mid-term exam. A preliminary course programme for 2017 can be downloaded here
Aims of the course
In stuctural optimization the problem of finding the 'optimal' design is considered. The term 'optimal' design can apply to various aspects and the common features are minimum weight or maximum stiffness of a structure. The course is aimed to give the student knowledge and fundamental understanding of modern tools that are commercially available.

Hint: The syntax for fminbnd is for example
lam=fminbnd(@(lambda) NegDualPhi(lambda,parameter1,parameter2 ....),lam_min,lam_max,OPT);
'OPT' represents a variables that might be supplied to the fimnbnd function, for example OPT=optimset('TolX',1e-12);
The geometry for the truss structure is given by geomSO.mat.
