Animal group formation has often been studied by mathematical biologists through PDE models, producing
classical results like traveling and stationary waves. Recently, Eftimie et al. introduced a 1-D PDE model
that considers three social interactions between individuals in the relevant neighborhoods, specifically re-
pulsion, alignment, and attraction. It takes into account the orientation of the neighbors when consider-
ing if they can communicate. This has resulted in exciting new movement behaviors like zig-zag pulses,
breathers, and feathers. In this work, we translate the Eftimie model into a Lagrangian implementation.
Currently, the results from the Lagrangian formulations show many of the results displayed by Eftimie’s
original PDE model, producing patterns like the zig-zag, breather traveling, and stationary pulses. In addi-
tion, we model animal movement with an ODE approach to complete the investigation regarding the role of
direction-dependent communication mechanism in discrete-space. / Applied Mathematics
