The absence of supplies interest is existed in recommendation algorithm

to address the issue in this paper Pareto Optimality is introduced and a modified two-sided algorithm is proposed.Firstly

it compares consumers demand and suppliers properties

then infers the consumers satisfaction.Secondly

it compares suppliers demand and consumers credit

then make sure the supplies satisfaction.The improved the G-S algorithm for consumers and sellers provides appropriate match according the consumers satisfy.Experiments show that the algorithm has high satisfy.
