<br>
i created a model and i want to expand it.
<br>
I want to add variables-columns which are binary(0-1).
<br>
How can i state it to Cbc in order not to be perceived as
continuous variables?
<br>
<br>
Thank you.

I found in the CBC user's guide, in the "Pseudo Cost Branching"
Chapter the sentence:<br>
<br>
<span style="color: rgb(0, 0, 0); font-family: 'Times New Roman';
font-size: medium; font-style: normal; font-variant: normal;
font-weight: normal; letter-spacing: normal; line-height: normal;
orphans: 2; text-align: start; text-indent: 0px; text-transform:
none; white-space: normal; widows: 2; word-spacing: 0px;
-webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;
display: inline !important; float: none; ">"If the user declares
variables as integer but does no more, then CBC will treat them as
simple integer variables."</span><br>
<br>
How can i declare a variable to be integer(binary 0-1)?<br>
<br>
I use the OsiClpSolverInterface and pass the model to the solver
with the method:<br>
<br>
<i>loadProblem(numcols, numrows, start, index, value, collb, colub,
obj, rowlb, rowub)</i><br>
<br>
Thank you<br>
