Constructor Detail

StudentSequence

public StudentSequence(int[] columns)

Constructor

Parameters:

columns - limits of sections of a course (e.g., new int[] {5, 10} for two sections, first of the size 5, second of the size of 10)

Method Detail

nrColumns

public int nrColumns()

limit

public int limit(int col)

Limit of a column (section of a course).

check

public boolean check()

Check that the underlying sequence is a valid sequence of students. I.e., that each student can be enrolled into a section.

Returns:

true, if valid

allow

public boolean allow(int x,
                     int col)

Check whether it is possible to allow student of given type into the given section. Student type can be seen as a binary string that has 1 for each section into which a student can be enrolled. I.e., student of type 0 can be enrolled into the fist section, type 2 into the second section, type 3 into both first and section section, type 4 into the third section, type 5 into the first and third section etc.

nrAllow

public int nrAllow(int x)

Number of sections into which a student of a given type can be enrolled (see allow(int, int) ).

maxCnt

public int maxCnt(int x)

Maximum number of student of the given type that can be enrolled into the provided sections (i.e., sum of limits of sections that are allowed fot the student of the given type, see allow(int, int)).
