The change button is used to change the structure of the
problem by changing the numbers of variables and/or constraints
or by changing the integer nature of the variables. The solver
option can also be changed.
The following result is obtained when all the variables
are required to be integer. Note that the letter I precedes
the index of each integer variable. For this case they are
all integer.
The LP/IP dialog has an entry that
indicates the number of leading variables that are to be integer.
The leading variables are those with the lowest indices. Variables
other that the leading ones can be made integer by placing the
letter I or any word beginning with I in the cells normally holding
the variable indices. The image below shows the solution when
the two leading variables are integer and P5 is made integer
by placing the word "integer" in its index field.
