Finite element inverse analysis using a photosynthetic algorithm

The reaction of carbon molecules in the dark reaction of photosynthesis was chosen as a biosystem-derived algorithm (BDA). This study refers to the BDA as the photosynthetic algorithm (PA). The PA utilizes the rules governing the transfer of carbon molecules from one substance into another in the Benson¯Calvin cycle and photorespiration reactions. The mechanism of PA is an organized random search biomimetically rationalized by photosynthetic processes. This paper presents the principles of the PA in detail. A finite element inverse analysis was selected as a typical optimization or parameter estimation problem to demonstrate the performance of the PA. The elastic moduli of a finite element model were successfully estimated from predetermined boundary conditions and observed deformation data.
