consider network(graph) of n nodes , each of them holding value, how design program/algorithm (for each node) allows each node compute average(or sum) of node values in network? assumptions are: direct communication between nodes constrained graph topology, not complete graph. other assumptions, if necessary algorithm, allowable. weakest 1 assume there's loop in graph contains nodes. n finite. n suffiently large such can't store values , compute average (or sum). same reason, can't "remember" value you've received (thus can't redistributing values you've received , add you've not seen buffer , result). (the tags may not right since don't know field kind of problems in, if it's kind of general problem.) that interesting question, here assumptions i've made, before present partial solution: the graph connected (in case of directed graph, connected) the nodes communicate direct neighbours it possible hold , send
