%description
Finds product portfolios that maximize TURF (total unduplicated reach and
frequency) with integer linear programming, following Serra (2013)
<doi:10.1016/j.foodqual.2012.10.001>. The maximum reach problem is the
maximal covering location problem of Church and ReVelle (1974)
<doi:10.1007/BF01942293>. The package solves it as an integer linear
program, so it finds exact optima without enumerating every portfolio.
Ties on reach are broken by frequency and then by the harmonic mean of the
individual product reaches. The package also finds the smallest portfolio
that reaches every reachable respondent. For related work on TURF for
large data sets, see Ennis, Fayle, and Ennis (2012)
<doi:10.1016/j.foodqual.2011.06.004>.
