Understanding human walking and teaching humanoid robots to walk in a human-like way is a challenging task in robotics. It is also one of the central goals of the European projects KoroiBot and H2R as well as the DARPA robotics challenge. To improve humanoid walking it is crucial to identify the essential characteristics of human movement and transfer it to robots. Different geometries and inertial properties of the human and humanoid systems including different kinematic and dynamic constraints have to be taken into account in this transfer.  Model-based optimization, reinforcement learning, movement primitives and neural primitives represent different bio-inspired approaches to motion generation for humanoid robots. The aim of this workshop is to present the different advantages of all these approaches as well as many promising works on combining them. Optimization or optimal control can be performed on robot and human models of different complexity taking different constraints into account, in both offline and online context. It is very useful for exploiting the physical limits of a system, but solutions might have to cope with model-reality mismatches which have to be addressed. Reinforcement learning can work without any model, iterating over reality, but in the contact of complex systems and motions that easily fail, it requires good starting data. Different types of movement primitives, such as kinematic or dynamic primitives (in different senses) provide a good approach  to standardize motions taking into account constraints. Neural primitives do not refer to the explicit motion but to the signal processing side of movement.  While there is a tight coupling between movement primitives and learning (although not reinforcement learning), since movement primitives are usually learned from human data, there are not yet many links nor between optimization and learning nor between optimization and movement primitives. In this workshop, state of the art methods in the fields of optimization, learning and primitives are presented, and a special focus is put on different possibilities of combining optimization methods with the other fields.
