Agent

The blop Agent takes care of the entire optimization loop, from data acquisition to model fitting.

from blop import DOF, Objective, Agent

dofs = [
    DOF(name="x1", description="the first DOF", search_domain=(-10, 10))
    DOF(name="x2", description="another DOF", search_domain=(-5, 5))
    DOF(name="x3", description="yet another DOF", search_domain=(0, 1))
]

objective = [
    Objective(name="y1", description="something to minimize", target="min")
    Objective(name="y2", description="something to maximize", target="max")
]

dets = [
    my_detector, # an ophyd device with a .trigger() method that determines "y1"
    my_other_detector # a detector that measures "y2"
]

agent = Agent(dofs=dofs, objectives=objectives, dets=dets)

This creates an Agent with no data about the world, and thus no way to model it. We have to start with asking the Agent to learn by randomly sampling the parameter space. The Agent learns with Bluesky plans emitted by the agent.learn() method, which can be passed to a RunEngine:

RE(agent.learn("qr", n=16)) # the agent chooses 16 quasi-random points, samples them, and fits models to them
