Paper A ( Two efficient algorithms for linear time suffix array construction ) is the main research field of Pro. Ge Nong ( issng@mail.sysu.edu.cn , Sun Yat-sen University, Guangzhou, 中山大学). It is also his first paper in this field. Sequent papers relevant of him are all based on this one. Paper B is  Space Efficient Linear Time Construction of Suffix Arrays . Paper A is found plagiarizing paper B.  Years ago, there were analyses by the researchers in the same field. See Suffix Array Construction: KA’s algorithm and Induced Sorting, which is faster? It gives a very polite comment in English after analysis. And 最好写的suffix tree（suffix array）算法？ The analysis in Chinese points out that the idea and logic of the algorithm (Setcion III. ALGORITHM I: INDUCED SORTING VARIABLE-LENGTH LMS-SUBSTRINGS, Page 3~8) in Pro. Ge Nong’s paper A are the same as the algorithm of paper B.

I started my Ph.D. program at the school of data and computer science, Sun Yat-sen University(SYSU, Guanzhou), in 2012. Student ID:12110646. I am one of the first batch  Ph.D. students(total 2) of Pro. Ge Nong (issng@mail.sysu.edu.cn). In 2012, after I entered into SYSU, Pro. ** talked to me times implying bribe demand, no avail. Then, I had to research alone for 7 years and must be close to his research field according to the clauses of the university, no direction, no advice, no machine, no support even there is national funding provided to the supervisor for each PhD student. In Apr. 2019, in the case of meeting the requirement of graduation, my last chance to apply for the degree, Pro. Ge Nong refused to sign relevant documents. And the local police station was asked to treat me as a concerned-object after my complaint to the department head. Later in Apr. 2019, I complained to the President's Office and the Office of Government Ethics of the university, then my thesis wa...
