Optimization Technique Abaqus and Isight

I would like to optimize a structure created and analysed using Abaqus in Isight. For a variety of inputs (truss radius, structure configuration etc) I would like to minimise the structural total mass extracted from Abaqus with a few constraints such as the local stress in the truss. I have 7 variables and 4 constraints with a single objective which is to minimize the total mass. My Abaqus Analysis takes approximately 10 minutes. Which one would be the most suitable Optimization technique amongst the techniques offered in Isight's Optimization Component? Thank you in advance!
