Fast structural optimization with frequency constraints by genetic algorithm using adaptive eigenvalue reanalysis methods (2011, methodology): “This example has been widely investigated in more detail by Grandhi (1993) using optimality algorithm, Sedaghati et al. (2002) using SQP technique in conjunction with the finite element force method, Wang et al. (2004) using evolutionary node shift methods as well as Wei et al. (2005 )u sing niche”
Sizing optimization of truss structures by method of centers and force formulation (2010, methodology): “The same force formulation was utilized in optimization under frequency constraints, which performed better than the displacement method (Sedaghati, 2005; Sedaghati et al., 2001, 2002).”
Shape optimization of structures for frequency constraints by sequential harmony search algorithm (2013, background): “This problem has been investigated by Sedaghati et al. (2002), Gomes (2011) and Kaveh and Zolghadr (2011).”
Truss optimization on shape and sizing with frequency constraints based on parallel genetic algorithm (2011, methodology): “This example has been investigated in detail by Grandhi and Venkayya (1988) using optimality criteria algorithm, Sedaghati et al. (2002) using SQP technique with the finite element force method, Wang et al. (2004) using evolutionary node shift methods, as well as Wei et al. (2005) using NHGA.”
