The main contributions of this paper include,(1) introduces the backtracking mechanism into traditional GEP methods and proposing a new algorithm named GEP with backtracking strategy.(2) Proposes the concept of Backtracking Checkpoint and designing Geometric Proportion Increased Checkpoint Sequence and Accelerated Increased Checkpoint Sequence to restrict the backtracking process.(3) Extends the GEPBS algorithm by introducing a Retrogression Factor to control the percentage of backtracking.(4) Proves the effectiveness of the new algorithm by two extensive experiments, which show that new method increases the max fitness by 49.2

本文的主要工作包括：（1）在传统GEP算法中引入回溯机制，提出基于回溯策略的GEP算法（GEP with backtracking strategy ，GEPBS）；（2）提出回溯检查点概念，设计了等比递增检查点序列和加速递增检查点序列用于约束回溯过程；（3）扩充基于回溯的GEP算法，设计了退化因子，提出了按比例回溯策略（GEP with proportional backtracking strategy， GEPPBS）（4）通过两个实验验证了新算法的有效性，在相同条件下较传统算法的适应度最大提高了49.2％，成功率最高提高了4倍

In this paper, 3ds model file format is analyzed and adopted as a primary representation of the geometric model in virtual environment. The feasibility and generality are investigated from the point of view of principle, practical application and experiment result. It is proved that, for application not very complex, it is a practical way to adopting 3ds model and relative 3-d modeling software to establ...
