| 08.02.2010 | Intermediate ResultMost students chose the first exam day (sorry for the long delays). The results will be submitted to the student office after the second exam date. |
| 02.02.2010 | Zusätzlicher PrüfungsterminDa sich jetzt doch mehrere Studenten gemeldet haben, dass sie am 8.2.2010 nicht zur Übung erscheinen können, bieten wir für den 15.2.2010 einen weiteren Prüfungstermin an. Jede Gruppe, die sich am Ersatztermin prüfen lassen möchte, sendet bitte eine Email mit den Namen der Gruppenmitglieder und dem Betreff "IMS-Prüfung" an lorenz@mathematik.tu-darmstadt.de, mit Kopie an brandenburg@mathematik.tu-darmstadt.de ederer@mathematik.tu-darmstadt.de opfer@mathematik.tu-darmstadt.de Bitte nutzen Sie auch die studentische Sprechstunde am Mittwoch für Fragen zu den Aufgaben. Am Montag werden wir vermutlich die gesamte Zeit für die Prüfungsabnahmen brauchen. Additional examination dateBecause several students contacted us that they cannot appear to the exercises on Feb. 8th 2010, we offer a further examination date. All groups who would like to make the exam on Feb 15th 2010, please, send an email with your group members and with the subject "IMS-Exam" to lorenz@mathematik.tu-darmstadt.de, and in copy to brandenburg@mathematik.tu-darmstadt.de ederer@mathematik.tu-darmstadt.de opfer@mathematik.tu-darmstadt.de There won't be any time to ask questions concerning the exercises on the examination dates! Please visit the office hours. |
| 02.02.2010 | Please check that your polynomial satisfies all six conditions. The denominator of one coefficient should be 1632960. |
| 02.02.2010 | For those of you who experience strange letters after the decoded text, please recheck that you don't scale any frequencies to zero for symbols that do appear in the string. Otherwise, some letters in the text might get lost. |
| 01.02.2010 | For those of you having problems with the C exercise: there's a short description of Huffman coding on binaryessence. If you are interested in binary heaps, see wikipedia. If you feel desperate, come to the Wednesday student office hours. |
| 01.02.2010 | 3.c) Hint: The package containing display is plots (not plot)! So you have to use with(plots);. |
| 28.01.2010 | Please test your C++-code with the file sample_text.txt from the Exercises section. |
| 28.01.2010 | Remember that the Maple-commands solve and fsolve can do a lot of magic for you - more than you might expect. |
| 27.01.2010 | Another hint for Exercise 3.h): The volume should be bigger than 235 and less than the volume of the glass. |
| 27.01.2010 | Someone asked about the 'uncompress' function of the C exercise: The argument 'size' specifies the char length of the uncompressed output 'string' (not the bit length of 'compressed'). The first integer of the compressed file 'testfile.bin' contains this value. The 'string' argument is initialized with the correct size, so that you only need to fill it. |
| 26.01.2010 | Remember that your variables do not remain in memory if you close your Maple-document and reopen it. You have to press the "!!!"-Button in order to reexecute your code. So do not delete any code that you might need later. |
| 25.01.2010 | If you want to get rid of the compiler warnings in the final exercise, just replace every apperance of "char* filename" by "const char* filename" (without quotation marks). You do not have to do this in order to solve the exercise. |
| 18.11.2009 | Someone asked for a contact email. Here it is: Feel free to ask any questions. |
| 11.11.2009 | Someone asked for the Computer Science SSH Gateways after the lecture. Here they are: clientssh1.rbg.informatik.tu-darmstadt.de clientssh2.rbg.informatik.tu-darmstadt.de |

Obtaining your Course Attendance Certificate
As announced in the first lecture, there is a homework assignment you have to work on in small groups (of about 3 people) in order to obtain your course attendance certificate. The homework assignment will be posted on the homepage and is due at the LAST exercise lab. The exercise will consist of a Maple and a C/C++ part. Further details will be on the exercise sheets.
