Claim 0:
1. A method of controlling an environment by selecting control settings that include a respective setting for each of a plurality of controllable elements of the environment, the method comprising repeatedly performing the following:
repeatedly selecting, by a control system for the environment, control settings for the environment based on internal parameters of the control system, wherein:
at least some of the control settings for the environment are selected based on a causal model that identifies, for each controllable element, causal relationships between possible settings for the controllable element and a performance metric that measures a performance of the control system in controlling the environment, and
the internal parameters include a first set of internal parameters that define a number of previously received performance metric values that are used to generate the causal model for a particular one the controllable elements, wherein the first set of internal parameters includes a window value that specifies the number of previous instances;
obtaining, for each selected control setting, a performance metric value;
determining, based on the measures of the performance metric values, that generating the causal model for the particular controllable element using a different number of previously received performance metric values would result in higher system performance, wherein the causal model includes a respective distribution around an impact measurement for each possible setting for the controllable element and wherein determining, based on the measures of the performance metric values, that generating the causal model for the particular controllable element using a different number of previously received performance metric valu es would result in higher system performance comprises updating the causal model based on the measures of the performance metric values; and
adjusting, based on the determining, the first set of internal parameters.
