We present a model of fuzzy logic programming with best answer semantics as an optimization task and discuss various utility function problems.

BACKGROUND Single Best Answer (SBA) questions are widely used in undergraduate and postgraduate medical examinations. Selection of the correct answer in SBA questions may be subject to cueing and therefore might not test the student's knowledge. In contrast to this artificial construct, doctors are ultimately required to perform in a real-life setting that does not offer a list of choices. This...

Massive Open Online Courses (MOOCs) have grown in reach and importance over the last few years, enabling a vast userbase to enroll in online courses. Besides watching videos, user participate in discussion forums to further their understanding of the course material. As in other communitybased question-answering communities, in many MOOC forums a user posting a question can mark the answer they...

one of the most important issues in the management of production is select the best option for each production activity, so that the time and cost of production is minimal and quality is the maximum. considering to the large number of activities and options for each activity, usually, this choice does not have a unique solution and can be used the utility function and assign weights to time, co...

Given a combinatorial search problem, it may be highly useful to enumerate its (all) solutions besides just finding one solution, or showing that none exists. The same can stated about optimal if an objective function is provided. This work goes beyond the bare enumeration of and addresses computational task solution by optimality (SEO). studied in context Answer Set Programming (ASP) where (op...
