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

The effect of single factor indicated that lower concentration of tea polyphenols and oxidant, temperature, ester proportion and pH value, shorter reaction time were favorable to the formation and accumulation of TFs, higher concentration of tea polyphenols, temperature, ester proportion and pH value, longer reaction time were favorable to the formation and accumulation of TRs.
借助参数模型研究各参数因子对TFs和TRs形成的影响,结果表明:茶多酚浓度、温度、酯比例及pH值对TFs和TRs形成与积累均有显著影响,反应时间对TFs影响显著,氧化剂对TRs影响显著;单因素效应显示:较低的茶多酚和氧化剂浓度、适当的低温和较短的时间、低的酯比例和pH较有利于TFs形成与积累,而有利于TRs形成与积累的参数则相反。

Physical activity is a well-recognized component of healthy lifestyles. Physical inactivity is a major risk factor for several chronic diseases. Although the benefits of regular physical activity on health have been well-demonstrated, the prevalence of physical inactive is still high in Taiwan. This study was designed to investigate the possible determinants of exercise participation. A stratified random sampling was applied to recruit subjects from seven districts in Tainan City.
体能活动是健康生活型态中很重要的一环,体能活动不足是许多慢性疾病的主要危险因子,虽然规律体能活动对健康的益处在近年来已经被国内外许多研究所证实,但国人没有运动习惯的比例仍然偏高,而本研究的目的是要了解影响民众从事运动行为的影响因子。
