1. A system comprising:

  • a solar thermal receiver having a plurality of panels;

    a plurality of heliostats configured to reflect flux from the Sun toward the solar thermal receiver; and

    a processor having an addressable memory, the processor configured to;

    receive a linear function comprising input parameters of maximizing an amount of heat absorbed by the solar thermal receiver;

    receive constraints comprising;

    a calculated total energy that a heliostat can contribute to the solar thermal receiver, a total amount of flux the solar thermal receiver can absorb, and the total amount of flux a panel of the solar thermal receiver can absorb;

    determine all of a full space of optimal solutions to the received linear function based on the input parameters and the constraints, wherein the full space of optimal solutions has a convex shape on a hyper-plane;

    select a point from in the full space of optimal solutions as a return variable, wherein small perturbations to the amount of heat absorbed by the solar thermal receiver produces small changes to the return variable; and

    select a desired set of tracking heliostats that satisfies the received linear function.
