Objetivos

This course aims to present a first reference to the modeling of real optimization problems, as well as to provide ample information about some of the techniques used to solve those problems. There will be an approach to the various themes according to the degree area, with a view to developing the ability to apply modeling and optimization techniques to real situations.

Métodos de ensino e atividades de aprendizagem

In the theoretical-practical classes are presented the basic concepts of the different subjects of the syllabus and the proofs of the main results, followed by problems solving. In this type of classes students will acquire an overview of the themes and their interconnections.

The achievement of Mathematics I can be obtained through two processes of assessment in person: Continuous Assessment and Assessment by Exam.



Continuous evaluation



Continuous assessment is based on two tests (with grades rounded to the nearest tenth). The conditions for passing the continuous assessment are as follows:



  • if the average (rounded to the units) of the test classifications is greater than or equal to 10 and less than 18, the student is approved with a final grade equal to that average, provided that in any of the tests the grade has been greater than or equal to 7.5 points;

  • if the average (rounded to the units) of the test classifications is greater than or equal to 18, the student will have to take an oral exam, the final grade being the average of these two grades. If you do not attend the oral exam, the final classification will be 17 points.






Recovery of one of the tests

The realization of the recovery of one of the tests is conditioned to the confirmation of its viability, given the spacing between the date of the 2nd test and the date of the exam of normal season.
The conditions for its realization will be as follows:





  • a student who has a grade greater than or equal to 7.5 in both tests, but an average lower than 10 values, has the option to perform the recovery of one of the tests, on the same day and time as the first season exam;

  • a student who has a grade lower than 7.5 in one of the tests, has not been able to take it or has given up, will only be able to perform the recovery of that test, on the same day and time of the first season exam if the other test has a grade greater than or equal to 7.5;

  • successful students cannot take a test recovery with a view to improving their grade.




Exam assessment

The assessment based on the completion of an exam will follow the usual rules, that is, students who choose not to perform continuous assessment, or who, having opted for it, have not been approved, may attend the regular exam periods.

The approval conditions are as follows:



  • if the exam grade (rounded to the units) is greater than or equal to 10 and less than 18, the student is approved with a final grade equal to the exam grade (rounded to the units);

  • if the exam grade (rounded to the units) is greater than or equal to 18, the student will have to take an oral exam, obtaining as a final grade the average of the marks of the referred oral exam and the exam. If you do not attend the oral exam, the final classification will be 17 points.



Fórmula de cálculo da classificação final

Let T1 and T2 be the test classifications rounded to tenths and CF=0.5T1x0.5T2 (rounded to units).

Avaliação especial (TE, DA, ...)

Students with special rights referred to in the Regulation of Academic Activities and Guidelines for Assessment and School Performance of IPS Students must, by the second week of the beginning of the semester, contact the person responsible for the curricular unit, to present their relevant specificities, under the terms provided for in the respective diplomas, otherwise they cannot be executed due to lack of objective conditions.

Melhoria de classificação

According to Article 11 of the Regulation of Academic Activities and Guidelines for the Assessment of Academic Performance of IPS Students, the improvement of classification may occur in the academic year of enrollment, at the time of appeal, or in the academic year following the of approval, in any period of assessment by examination, except for the special period.

Observações

Rules for conducting assessment tests/exams:



  • During the assessment tests/exams, the presentation of an oficial identification document with a photograph will be mandatory.

  • Students must take the tests/exams in their own IPS notebooks, for which they must first acquire a notebook from reprography (with 1 cover and 4 continuation sheets).

  • The handling or display of mobile phones, or any other means of remote communication, during the test is not allowed, which is sufficient reason for the cancellation of the assessment test, regardless of whether they were used.

  • The use of calculators is allowed.

  • A form is allowed for consultation during the tests and will be made available in Moodle in advance.

  • Leaving the room can only take place one hour after the start of the test/exam and will imply the final delivery of the test/exam.

  • Exams or questions written in pencil are not accepted.

  • It is not allowed to use a corrector pen in test/exam.



____________________
Informations:



  • Office hours will be published in Moodle.

  • The CU will have all the information and specific materials in the Moodle platform. 

  • Communication with students is made exclusively to the institutional address (@estudantes.ips.pt). It is up to the student to consult their area in the information system, on the course page in Moodle, as well as to manage and periodically consult their email account in the IPS domain, using it to communicate with the IPS services.
