The exams will be returned to the secretary tomorrow. All the grades, including the final grades, appear now in GR. The final grades include a factor of 5 points added to the exam grade (note that the exam grades appear as they are, and the factor is seen in the final grade calculation only). If you wish to appeal on the exam grade, please submit the appeal till 27/10 to Emilia's mailbox on the 5-th floor (number 79), and please use the standard form. Please appeal only on factual errors, e.g., if you answer is correct but was marked as wrong, or if there was an error in points summation. Please do not appeal on the number of points taken off for a mistake, as the same grading policy was applied to all the students. --Course staff. |

Solution to Spring 2005 MoedA question 1.1 | |
(The question is solved under the assumption that lower(s) and upper(s) may have independent values not related to a/b values.) Suppose that lower(a) = 3sec, lower(b) = 5sec, and lower(s) = 10sec. It means that we should be in state 'a' at least 3 sec, in state 'b' at least 5 sec, and in the super state 's' at least 10 sec. Since we deal with parallel components, each of the lower constraints should be satisfied and therefore: lower(actual) = max{lower(a), lower(b), lower(s)} // in our example lower(actual) = 10sec Calculating upper(actual) is similar but with relating to the minimal value: upper(actual) = min{upper(a), upper(b), upper(c)} The reason is that we can't actually stay longer than the minimal upper constraint. One last point, for the actual values to be reasonable, lower(actual) should be lower than upper(actual). |

Realtime Clarification | |
The expression: q U[x,y] p Means that p will NOT happen before x time unites pass and will happen before AT MOST y time unites pass. This implies (due to the Until operator) that also q will be true for at least x time unites (since it must hold until p holds). There is no limitation to how long can q last beyond x (since Until does not demand this). |

Rhapsody problem is fixed - DO NOT use Rhapsody in C++ | |
A problem occurred in the previous installation of Rhapsody therefore we installed the Rhapsody Java edition which is called 'Rhapsody in J'. The main difference in the Java version is that any code added to the statecharts should be Java code and not C++ code as previously explained. The self tutorial file was updated accordingly so make sure you use its updated version. The file tutorial.zip was also replaced with tutorialJava.zip. -- Course staff |

A technical problem - Rhapsody installation | |
There is a technical problem in the Rhapsody installation in the pc farm that prevents running the statechart simulation (and thus most of the self tutorial). The cause for the problem was found but it will be fixed only on Wednesday-Thursday. We sorry for that, and those of you who wish to start with the exercise can start by planning the statechart/s, and then migrate the solution to Rhapsody when the problem is fixed.
