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

Through statical analysis of the data dependency between subgoals, combined with the analysis results of the characteristic of parallel execution and the impacts of side-effects, the intelligent backtracking points with conditions can be found in precompiling time. At run time, the intelligent backtracking points for failed goals can be determined by variable testing and run state testing. Using intelligent backtracking scheme, a lot of redundant backtracking can be avoided and the execution efficiency of programs is improved.

同时，我们在深入研究顺序智能回溯及并行平凡回溯机制的基础上，独立提出了一种并行智能回溯机制，通过静态时对子目标数据相关性的分析，结合对并行执行特性及付作用目标对智能回溯的影响等因素的分析，产生带条件的智能回溯点；动态时通过对变量及当前运行状态的简单测试，确定失败目标的智能回溯点。

Traditional GEP Algorithm may leads to prematurity by local optimum trap . In order to solve the premature convergence problem, this paper proposes a novel GEP method based on backtracking referring to the atavism in the biosphere.

传统GEP可能陷入局部最优的"早熟"陷阱，为解决基因表达式编程中的未成熟收敛问题，本文借鉴生物界的"返祖现象"，提出了基于回溯的基因表达式编程方法，有效地改善了传统算法在进化过程中的早熟现象。

backtracking：回溯

本研究以回溯(backtracking)的观念,建立模糊时间序列间确定状态移转关系,藉以控制预测不确定性(uncertainty)的发生. 图1为 F(t) 与 F(t-1) 为以回溯观念所建立的模糊关系,其中 F(t)、F(t-1) 为模糊时间序列,F(t) 为由 F(t-1) 所导致的结果.
