"
Given
a
set
P
of
polygons,
not
necessarily
convex,
and
a
rectangle,
\
\
we
want
to
find
the
subset
S
of
P
with
largest
possible
total
area
and
a
position
\
\
every
p
in
S
so
that
there
are
no
overlaps
and
they
are
all
included
in
the
rectangle.
\
\
We
allow
a
small
set
of
rotations
(0,
90,
180,
270
degrees)
for
every
polygon.
\
\
The
problem
is
simplified
w.r.t.
the
real
application
because
the
polygons
do
\
\
not
have
(fully
encircled)
\"
holes
\"
,
which
are
supposedly
filled-in
separately,
\
\
although
they
can
have
\"
bays
\"
.
\r\n\r\n
Models
are
saved
as
.lp.
Instance
LpPackingModel<X>_Dim<Y>
\
\
means
that
we
are
trying
to
pack
<Y>
polygons
taken
from
set
<X>;
there
are
currently
\
\
5
different
sets,
and
<Y>
is
7,
10
or
15.
