In case someone is interested, I have a brand new article comparing optimization tools in Grasshopper (Galapagos, Goat, Silvereye, Octopus, and Opossum).
You can go to ResearchGate and request a private copy there:
https://www.researchgate.net/publication/321346979_Model-based_Optimization_for_Architectural_Design-Optimizing_Daylight_and_Glare_in_Grasshopper
I also have a couple of other papers on there that are related to optimization in Grasshopper.
Otherwise, send me a message with your email, and I’ll send you a copy.
