Least squares shadowing sensitivity analysis of a modified Kuramoto–Sivashinsky equation.

Highlights: [•] Modifying the Kuramoto–Sivashinsky equation and changing its boundary conditions make it an ergodic dynamical system. [•] The modified Kuramoto–Sivashinsky equation exhibits distinct dynamics for three different ranges of system parameters. [•] Least squares shadowing sensitivity analysis computes accurate gradients for a wide range of system parameters. [ABSTRACT FROM AUTHOR]
