delta

delta&lt;-

Used by <code>psolve()</code> with <code>requires_grad = TRUE</code> and
<code>Problem$derivative()</code>. On a <code>Parameter</code>, the user sets <code>delta</code>
to a perturbation of the parameter's value; <code>derivative()</code> then
reports the predicted change in each <code>Variable</code>'s optimal value
as <code>delta(variable)</code>.

An object-oriented modeling language for disciplined
convex programming (DCP) as described in Fu, Narasimhan, and Boyd
(2020, <doi:10.18637/jss.v094.i14>). It allows the user to
formulate convex optimization problems in a natural way following
mathematical convention and DCP rules. The system analyzes the
problem, verifies its convexity, converts it into a canonical
form, and hands it off to an appropriate solver to obtain the
solution. This version uses the S7 object system for improved
performance and maintainability.
