A.1.RI:4.3 - Construct the materially different connections

Construct the associations still possible under the available account. A connection states which observations concern the continuing object and how the subject rules permit the intervening change. In a small finite case, listing the alternatives can be enough. Larger cases can use the domain’s assignment, constraint or probabilistic Methods.

Include a missed observation, new object, ended object or reused identifier when the observed situation and subject rules make that alternative live. For example, a process can terminate between reports and its number can later be reused. A fixed two-object motion exercise can instead supply persistence and complete detection as premises.

When several objects share observations, construct complete associations for the relevant group. Retain the conditions linking their choices. For independent point motions a pair of admissible paths may suffice; interacting bodies can require a joint evolution satisfying their interactions.
