In order to improve the efficiency of the Gene Regulatory Networks(GRNs)reconstruction,a novel algorithm based on hybrid parallel genetic algorithm and threshold value method was proposed.Two parts were included in this algorithm,the solution decomposition and parameter calculation.In solution decomposition,Singular Value Decomposition(SVD)method was used toobtain the solutions,which are capable in math framework.The threshold value method was used to reduce the unnecessary edges in the network,which can im...
