We propose an alternative reconstruction for weighted essentially non-oscillatory schemes with adaptive order (WENO-AO) for solving hyperbolic conservation laws. The alternative reconstruction has a more concise form than the original WENO-AO reconstruction. Moreover, it is a strictly convex combination of polynomials with unequal degrees. Numerical examples show that the alternative reconstruction maintains the accuracy and robustness of the WENO-AO schemes.

翻译：我们建议对具有适应性(WENO-AO)的加权非刺激性计划进行替代重建,以解决双曲保护法。替代重建的形式比原WENO-AO重建更为简洁。此外,它严格地将多元性与不平等度相结合。 数字实例表明替代重建保持了WENO-AO计划的准确性和稳健性。
