1. A computer-implemented method for radiotherapy treatment planning, the computer-implemented method comprising:
accessing a radiotherapy treatment plan including a plurality of treatment layers, each treatment layer of the plurality of treatment layers including a plurality of spots;
receiving a weight for a treatment time objective of the radiotherapy treatment plan;
modifying a spot from a treatment layer of the plurality of treatment layers based on the weight and a cost of the spot, to produce a modified treatment layer; and
generating a modified radiotherapy treatment plan using the modified treatment layer, wherein the modified radiotherapy treatment plan is operable to be executed by a delivery machine to apply radiotherapy treatment to a target in accordance with the modified radiotherapy treatment plan.
