Cuckoo search via Lévy flights for the capacitated vehicle routing problem

Santillan, Jon Henly; Tapucar, Samantha; Manliguez, Cinmayii - In: Journal of industrial engineering international 14 (2018) 2, pp. 293-304

For this paper, we explored the implementation of the cuckoo search algorithm applied to the capacitated vehicle routing problem. The cuckoo search algorithm was implemented with Lévy flights with the 2-opt and double-bridge operations, and with 500 iterations for each run. The algorithm was...

Risk return trade-off in relaxed risk parity portfolio optimization

Gambeta, Vaughn; Kwon, Roy - In: Journal of risk and financial management : JRFM 13 (2020) 10/237, pp. 1-28

This paper formulates a relaxed risk parity optimization model to control the balance of risk parity violation against the total portfolio performance. Risk parity has been criticized as being overly conservative and it is improved by re-introducing the asset expected returns into the model and...
