Is it possible to implement the following as part of an objective and if so how would I represent it, removing the '-' at the beginning of course:
<div><br>

<p>I tried the following and was getting an 'unexpected SYMBOL_VAR' error:</p>
<p><br>
</p>
<p>sum{ t in T, s in S : I[t,s] * c[s] * (m[t,s] - sum{ r in R, k in K : w[r,t,k] * x[r,t,k] })}</p>
<p><br>
</p>
<p>In the function x[r,t,k] is a variable, everything else is a parameter.</p>
