1. (20 pts) WYSIWIS ("What You See Is What I See") depicts agreement among distributed software agents in a collaborative networked system: namely, what consistent values of shared data/state the agents see at designated time-intervals . Examples of shared state are: i) location of robo-players \& ball in a soccer field; ii) product inventory in an online store for shopping by customers; iii) presence of hostile object in a terrain under surveillance by drones. Suppose the agents agree on a value Vt a time t - thereby triggering a collective action A(Vt,t) at time t>t that persists for time-duration (e.g., moving of items to a shopping cart in online purchase, kicking of ball in robot soccer game, taking of terrain picture by a drone's on-board camera). WYSIWIS enforces agreement among agents on a new value of data/state Vt+ due to the action A, where (t+)
