title: Restricting one variable in my variable vector to integer in Pyomo
body: <p>I have a minimization problem that currently has only continuous variables</p>
  
  <pre><code>min Cx
  s.t. Ax &lt;= b
  lb &lt;= x &lt;= ub
  </code></pre>
  
  <p>Where C is my cost vector, A is my coefficient matrix and b is my fixed vector. X is my variable vector of continuous variables.</p>
  
  <p>A = 24x29, x = 29x1, b = 24x1</p>
  
  <p>I want to force one of the x variables to be an integer, how can that be done in Pyomo?</p>
  
  <p>I am new to the package, any help is appreciated</p>
