Notes

Conference Helper BDI Agent outputs six lists and the current date. We call this output a summary. Summary includes the following lists:

begin{enumerate}
item List of BELIEFS: We define a belief as an event broadcasted by a service or proposal from an acquaintance. Each belief has a description and a date associated to it. We sort our list of beliefs w.r.t. their dates.
item List of FUTURE INTENTIONS: We define an intention as an action which is triggered by a belief and related to a desire. Conference Helper BDI Agent generates a list of intentions that are expected to be completed in the future, which we call FUTURE INTENTIONS or in short, a plan. Conference Helper BDI Agent aims to maximize the utility of its user while generating this plan.
item List of COMPLETED INTENTIONS: If a FUTURE INTENTION is not dropped, and the current date passes the date of the intention, we assume that the user completed this intention.
item List of SATISFIED DESIRES: A desire is a construct formed by a rank (an integer), and a description. We use ranks to sort all desires. Lower rank means higher utility for the user, if the desire is satisfied. We use descriptions to find which intentions satisfy which desires.
item List of FUTURE DESIRES: Conference Helper BDI Agent keeps a list of desires that are expected to be satisfied in the future. Conference Helper BDI Agent derives this list by looking at the FUTURE INTENTIONS list.
item List of FUTURE DESIRES TO FORGET ABOUT: There may be desires that are not going to be satisfied by the plan Conference Helper BDI Agent comes up with. We put these desires into the list of FUTURE DESIRES TO FORGET ABOUT.
end{enumerate}

For the sake of simplicity, we discretize the time as follows. Each day has a morning (09:00) and an evening (18:00) slot. Although this may not seem realistic, it's trivial to create higher number of slots for each day.

At each time $t$, Conference Helper BDI Agent outputs its summary. We call the time between each consecutive $t$ an epoch. This is because cancels, date changes, and all other unexpected situations arrive between each epoch.
