The model consists of a system of partial differential equations whose parameters reflect the movement behavior of individuals within each pack and whose steady-state solutions describe the patterns of space-use associated to each pack. By controlling the behavioral parameters in a spatially-dynamic fashion, packs adjust their patterns of movement so as to find a Nash-optimal balance between spreading their territory and avoiding conflict with hostile neighbors. On the mathematical side, we show that solving a nonzero-sum differential game corresponds to finding a non-invasible function-valued trait. From the ecological standpoint, when movement behavior is uncertain, the resulting evolutionarily stable equilibrium gives rise to a buffer-zone, or a no-wolf’s land where deer are known to find refuge.

Sedikit berbeda dengan komikus, ilustrator, atau -katakanlah-karikaturis yang menangkap suatu momentum ke dalam sebuah gambar diam (still). Animator harus lebih memiliki "kepekaan gerak" daripada "hanya" sekedar kemampuan menggambar. Gambar yang bagus akan percuma tanpa didukung kemampuan meng-"hidup"-kan. Sebagaimana definisi dasar animasi yang berarti: membuat seolah-olah menjadi hidup.
