Abstract

In an embodiment, a network may represent a physical system. The network may have an element that represents an entity of the physical system. A value of a state associated with the network may be identified (e.g., generated) using various techniques. The state may be a low-level state associated with the network. The techniques may include, but are not limited to, for example, generating the value based on a scaffold defined for the network, generating the value based on a target value for the state, and/or generating the value based on applying an operation to various values of the state. The identified value may be associated with an identifier. The identifier may distinguish the value, for example, from other values of other states in the network and/or other values of states in other networks.
