== Система оценки ==

Оценка за весь курс: 0.3 * ДЗ1-5 + 0.3 * ДЗ6-10 + 0.1 * Семинары + 0.3 * Экзамен

Оценка за может быть выставлена автоматом, если выполнены два условия:
* текущая оценка ((0.3 * ДЗ1-5 + 0.3 * ДЗ6-10 + 0.1 * Семинары) / 0.7) >= 8
* оценка за семинары >= 8

Автоматом выставляется текущая оценка.

Округление происходит один раз, при выставлении оценки за весь курс

== Защита ДЗ 1-5 ==

Защита ДЗ 1-5 состоится 20.09 с 16:20 до 17:40 в онлайн-формате с использованием прокторинга. Прокторинг как на курсах ОиМП: http://wiki.cs.hse.ru/%D0%9A%D0%A0_1_%D0%9E%D0%B8%D0%9C%D0%9F-3_2021

Форма для сдачи записанных видео: -

На защите ДЗ разрешается использовать эту вики-страницу, конспект, сайт https://en.cppreference.com/w/, а также свои решения задач из контестов с домашними заданиями.

Предварительная оценка за ДЗ 1-5 (обозначатся в формулах как ДЗ) считается как средняя оценка за все ДЗ с 1 по 5 включительно. Защита ДЗ 1-5 состоит из 5 задач. Итоговая оценка за ДЗ 1-5 определяется следующим образом:

* Если на защите решено 0 задач: ДЗ * 0.25

* Если на защите решена 1 задача: min(ДЗ, max(0, 2 + (ДЗ - 2) * 0.25))

* Если на защите решено 2 задачи: min(ДЗ, 4 + max(0, (ДЗ - 4) * 0.5))

* Если на защите решено 3 задачи: min(ДЗ, 6 + max(0, (ДЗ - 6) * 0.75))

* Если на защите решено 4 задачи: ДЗ

* Если на защите решено 5 задач: min(ДЗ + 2, 10)

В таблице показаны примеры применения формулы для целочисленных значений ДЗ:

|-

|-
|}

== Экзамен ==

Экзамен пройдет в устном формате.

Студенту будет предложены простые вопросы, отвечать на которые нужно без подготовки: “как работает алгоритм Дейкстры на данном входе?”, “как реализовать lower_bound в двоичном дереве поиска?”, “какие шаги будут при сортировке данного массива слиянием?” и т. п.

Тематика вопросов совпадает с темами лекций.

Если у студента есть автомат, либо студент не желает приходить на экзамен, то на экзамен можно не приходить (в последнем случае в ведомость будет выставлена неявка, что эквивалентно оценке 0).

== Course Description ==
The course introduces students to the elements of linear algebra and analytic geometry, provides the foundations for understanding some of the main concepts of modern mathematics. There is a strong emphasis in this course on complete proofs of almost all results.

We will approach the subject from both a practical point of view (learning methods and acquiring computational skills
relevant for problem solving) and a theoretical point of view (learning a more abstract and theoretical approach that focuses on achieving a deep understanding of the different abstract concepts).

Topics covered include: matrix algebra, systems of linear equations, permutations, determinants, complex numbers, fields, abstract vector spaces, bilinear and quadratic forms, Euclidean spaces, some elements of analytic geometry, linear operators.

== Grading system ==

During the academic year, the student will be formally graded on the following:
*two in-class oral tests (O1 and O2);
*two in-class written tests (W1 and W2);
*several quizzes (Q1 and Q2, where Qi is the average grade of all the quizzes in the i-th semester);
*several homework assignments (H1 and H2, where Hi is the average grade of all the homework assignments in the i-th semester);
*two written exams (E1 and E2).

All grades (namely, O1, O2, W1, W2, Q1, Q2, H1, H2, E1, and E2) are real numbers from 0 to 10.

'''The cumulative course grade for the first semester''', C1, is obtained '''without rounding''' by the following formula:

'''C1 = 5/16*O1 + 4/16*W1 + 4/16*Q1 + 3/16*H1.'''

'''The intermediate course grade for the first semester''', I1, is obtained by the following formula:

'''I1 = Round1(3/10*E1 + 7/10*C1),'''

where the function Round1(x) is defined as follows: if the decimal part of x is less than 0.2, the grade is rounded downwards; if the decimal part of x is greater than 0.6, the grade is rounded upwards; if the decimal part of x is from the interval [0.2;0.6] and the student's seminar attendance during the first semester is not below 60%, the grade is rounded upwards; otherwise the grade is rounded downwards.

'''The cumulative course grade for the second semester''', C2, is obtained '''without rounding''' by the following formula:

'''C2 = 5/16*O2 + 4/16*W2 + 4/16*Q2 + 3/16*H2.'''

'''The intermediate course grade for the second semester''', I2, is obtained by the following formula:

'''I2 = Round2(3/10*E2 + 7/10*C2),'''

where the function Round2(x) is defined as Round1(x) but with "during the first semester" replaced by "during the second semester".

'''The final grade for the course''', F, is obtained by the following formula:

'''F = Round(1/4*I1 + 3/4*I2),'''

where the function Round(x) is defined as Round1(x) but with "during the first semester" replaced by "during the academic year".

The final grade for the course is included in a diploma supplement.

== Course Description ==
The course introduces students to the elements of linear algebra and analytic geometry, provides the foundations for understanding some of the main concepts of modern mathematics. There is a strong emphasis in this course on complete proofs of almost all results.

We will approach the subject from both a practical point of view (learning methods and acquiring computational skills
relevant for problem solving) and a theoretical point of view (learning a more abstract and theoretical approach that focuses on achieving a deep understanding of the different abstract concepts).

Topics covered include: matrix algebra, systems of linear equations, permutations, determinants, complex numbers, fields, abstract vector spaces, bilinear and quadratic forms, Euclidean spaces, some elements of analytic geometry, linear operators. It took mathematicians at least two hundred years to comprehend these objects. We plan to accomplish this in one year.

== Grading system ==

During the academic year, the student will be formally graded on the following:
*two in-class oral tests (O1 and O2);
*two in-class written tests (W1 and W2);
*several quizzes (Q1 and Q2, where Qi is the average grade of all the quizzes in the i-th semester);
*several homework assignments (H1 and H2, where Hi is the average grade of all the homework assignments in the i-th semester);
*two written exams (E1 and E2).

All grades (namely, O1, O2, W1, W2, Q1, Q2, H1, H2, E1, and E2) are real numbers from 0 to 10.

'''The cumulative course grade for the first semester''', C1, is obtained '''without rounding''' by the following formula:

'''C1 = 5/16*O1 + 4/16*W1 + 4/16*Q1 + 3/16*H1.'''

'''The intermediate course grade for the first semester''', I1, is obtained by the following formula:

'''I1 = Round1(3/10*E1 + 7/10*C1),'''

where the function Round1(x) is defined as follows: if the decimal part of x is less than 0.2, the grade is rounded downwards; if the decimal part of x is greater than 0.6, the grade is rounded upwards; if the decimal part of x is from the interval [0.2;0.6] and the student's seminar attendance during the first semester is not below 60%, the grade is rounded upwards; otherwise the grade is rounded downwards.

'''The cumulative course grade for the second semester''', C2, is obtained '''without rounding''' by the following formula:

'''C2 = 5/16*O2 + 4/16*W2 + 4/16*Q2 + 3/16*H2.'''

'''The intermediate course grade for the second semester''', I2, is obtained by the following formula:

'''I2 = Round2(3/10*E2 + 7/10*C2),'''

where the function Round2(x) is defined as Round1(x) but with "during the first semester" replaced by "during the second semester".

'''The final grade for the course''', F, is obtained by the following formula:

'''F = Round(1/4*I1 + 3/4*I2),'''

where the function Round(x) is defined as Round1(x) but with "during the first semester" replaced by "during the academic year".

The final grade for the course is included in a diploma supplement.
