  We consider a linear non-local heat equation in a bounded domain
$\Omega\subset\mathbb{R}^d$, $d\geq 1$, with Dirichlet boundary conditions,
where the non-locality is given by the presence of an integral kernel.
Motivated by several applications in biological systems, in the present paper
we study some optimal control problems from a theoretical and numerical point
of view. In particular, we will employ the classical low-regret approach of
J.-L. Lions for treating the problem of incomplete data and provide a simple
computational implementation of the method. The effectiveness of the results
are illustrated by several examples.
