  Complex structure formation and fast focusing of light inside or through
turbid media is a challenging task due to refractive index heterogeneity,
random light scattering and speckle noise formation. Here, we have proposed a
weighted-mutation assisted genetic algorithm (WMA-GA) with an R-squared metric
based fitness function that advances the contrast, resolution, focuses light
tightly and does fast convergence for both simple and complex structure
formation through the scattering media. As a compatible system with the binary
WMA-GA, we have presented a fast, cost-effective, and robust iterative
wavefront shaping system design with an affordable ferroelectric liquid crystal
(FLC) based binary-phase spatial light modulator (SLM). The proposed wavefront
shaping system design has been used to construct multiple complex
hetero-structures simultaneously in 3D volume by an optimized single
phase-mask. The WMA-GA and the prototype system have been validated with 120,
220, 450, and 600 grit ground glass diffusers along with 323, 588, and 852
{\mu}m thick fresh chicken tissues including fluorescence in it. We have
demonstrated the robustness of the proposed method to control the photon-in and
photon-out from a localized fluorescent dye embedded in the tissue. The
detailed results show that the proposed class of algorithm-backed integrated
system converges fast with higher contrast and advances the resolution.
