Changelog

Added

• Added COSMOS from Scalable Pareto Front Approximation for Deep Multi-Objective
  Learning (ICDM 2021), a Scalarizer that combines a linear
  scalarization with a cosine-similarity penalty pulling the vector of values toward a preference
  direction.
• Added PBI (Penalty-based Boundary Intersection) from MOEA/D: A Multiobjective Evolutionary
  Algorithm Based on Decomposition (IEEE TEVC 2007), a
  Scalarizer that decomposes the values into a component along a preference direction and a
  penalized perpendicular component.
