  Collection of self-propelled particles (SPPs) exhibit coherent motion and
show true long-range order in two-dimensions. Inhomogeneity, in general
destroys the usual long-range order of the polar SPPs. We model a system of
polar self-propelled particles with inhomogeneous interaction strength or bond
disorder. The system is studied near the order-to-disorder transition for
different strengths of the disorder. The nature of phase transition changes
from discontinuous to continuous type by tuning the strength of the disorder.
The bond disorder also enhances the ordering near the transition due to the
formation of a homogeneous flock state for the large disorder. It leads to
faster information transfer in the system and enhances the system information
entropy. Our study gives a new understanding of the effect of intrinsic
inhomogeneity in the self-propelled particle system.
