Introduction: Two of the stories mentioned in the Qur'an are the story of Adam and the Forbidden Tree and the Story of Moses going to the Right Side of the Valley and hearing the Tree. These stories are of much interest to the scholars and mentioned in many of the mystic texts and commentaries in prose and verse such as Meibodi's Kashaf al-Asrar, Tamhidat of Ein al-Ghozat, works of Ruzbehan Baqli, Shabestari's Golshan-e Raz, Mathnavi of Mowlavi, Mersad al-Ebad of Najm al-Din Razi and many more. The Tree in both stories is a mystical symbol. In this paper the symbolic meanings of these two Trees are analyzed and compared.This is a comparative study of two symbols in religious and mystical texts. The Qur'anic symbol of Tree (forbidden and Moses') are analyzed. Discussion: In many instances such as verse 35 of Baqara, verse 19 of 'Iraf and verse 12 of Taha, the Qur'an refers to the story of Adam and the Forbidden Tree. Mystics have interpreted the Forbidden Tree as the physical world, divine secrets, the knowledge of destiny and fate, wisdom, love and union.Seid Heidar Amoli considers the Forbidden Tree the symbol of the physical world which will result in leaving the Garden of Eden. Aziz al-Din Nasafi considers the Forbidden Tree as the Tree of wisdom and a reminder of free will; the result of this free will is doubt and only love of God can free man from doubt. In 'Araes al-Bayan and Sharh-e Shatthiyat Ruzbehan regards the Tree as the secret of love. Attar referring to verse 35 of Baqara believes that the Tree is the Tree of union. Meibodi says that union as a sign of the Forbidden Tree also reminds one of the pain and suffering of proximity.In verse 30 of Qisas the story of Moses and his departure to the Right Side of the Valley is told. The Tree of Moses has allegorical meanings such as absolute existence, the sacred soul of man, the light of Mohammad (PBUH), the power of thinking, love, knowledge, monotheism and union. Seid Heidar Amoli and Ruzbehan consider the Tree of Moses as the absolute existence.Conclusion: Revelation has descended in a multidimensional language. Mystics have interpreted Qur'anic stories from different points of view due to their allegorical meanings. Interpretations of the mystics show that the Forbidden Tree means love and the Tree of Moses means the sacred soul of man. According to mystics these stories are abstract concepts such as love, wisdom, knowledge and union. Different intuitions, mystical experiences and interpretation of Qur'anic verses by different mystics have led to a rich body of literature which testifies to the still hidden meanings of the Divine subject.

In this paper, we develop a non-visual automatic wrapper to extract data records from search engine results pages which contain important information for computer users. Our wrapper consists of a series of data filter to detect and remove irrelevant data from the web page. In the filtering stages, we incorporate two main algorithms which are able to check the similarity of data records and to detect and extract the correct data region based on their component sizes. To evaluate the performance of our algorithm, we carry out experimental and deletion tests. Experimental tests show that our wrapper outperforms the existing state of the art wrappers such as ViNT and DEPTA. Deletion studies by replacing our novel techniques with state of the art conventional techniques show that our wrapper design is efficient and could robustly extract data records from search engine results pages. With the speed advantages, our wrapper could be beneficial in processing large amount of web sites data, which could be helpful in meta search engine development.

Shahnameh is a unique text that has been challenged by scholars in the field of Shahnameh due to the fact that the text and vocabulary of the text are old, as well as its rare words. In the part of Shahnameh, which is related to Zal's performance against Manuchehr, a bit has come in this sense. Zal threw a beam when the horse was running, and that shot struck the lion's Tree and penetrated it. Of course, in some of Shahnameh's books, instead of the lactating Tree, the lion's sword has come. Those who brought this term and the commentators of Ferdowsi's poetry who took milk in the sense of a wild animal have not been aware of one point. The point is that the ancient Persian poets of livestock did not rhymes in the meaning of the wildlife, because their pronunciation varies in the word "ya". Nardshir is here in the sense of lumbering Trees that comes out of gum and sap. The similarity of the milk in the meaning of the jungle animal and drinking liquid milk caused this mistake in the versions. In the story of Siavash, the word Nordshir is distorted to the green Tree.

In some communities, Tree had been revered and worshiped. Tree in its oldest vision is a giant cosmic Tree, which is the symbol of the universe and Creation. With regards to the close relationship between the Tree and human life, many communities have attributed a sense of sanctity to the Tree.The relationship between the man, the Tree and its holiness was in a way that people in some communities believed man was born from the Tree. This belief affected a part of the ritual, magic and aesthetic ceremonies of some nations. On the other hand, in some images, this is the Tree which has grown out of the human body.The Talking Tree and Wak Wak Tree are instances of legendary Trees which have entered into the Islamic art and culture.The different forms of illustrations of Wak Wak which have been drawn by Iranian painters depict the blend of the decorative and imaginative compositions in a beautiful manner. In this article, we aim to find out answers to the following questions:1- What is the similarity between the Tree and the man in the beliefs and legends of different nations?2- What is the relationship between the sacred Tree, the Tree of life, Talking Tree, and Wak Wak’s forms?Hypothesis: The common capabilities of man and Tree can be mentioned as fertility, growth and procreation. Tree has been posed as a symbol of fertility and procreation besides the man, thus there exists a close relationship between these two creatures, which has led to the creation of extraordinary myths. With regard to this issue, the sacred Tree, the Tree of life, the talking Tree and the Wak Wak Tree with the human and animal fruits have resulted into the formation of Wak Wak through a process.This research aims to understand the relationship between the Tree and human thoughts as well as the public beliefs reflected in fictions and various forms of arts.It may be interesting to note that few studies have been carried out in this field in Iran and they mostly described Wak Wak’s forms.

The Steiner Tree problem in a weighted graph is to find a least cost sub Tree in the graph such that it contains special vertices called terminal points. The Steiner Tree problem on graphs is one of the best-known NP-hard problems. For this reason, many approximation algorithms for solving steiner Tree problem have been proposed. The traditional algorithms achieve near optimal results, but cost more computational time. In this paper we propose an iterative algorithm based on learning automata for solving dynamic Steiner Tree problem. Simulation results show that our proposed algorithm generates Steiner Trees of low cost in reasonable running time.

Bakhtiari carpet has been less studied and introduced in art studies. Compared with other carpets, its rich designs and forms are overlooked by researchers. In this study an attempt is made to investigate the value and significance of Trees in Bakhtiari carpets, with emphasis on variety of its designs and forms.

In this article, holy manifestations of Tree, as the symbols of human and his wishes; have been taken into account, and been compared with myths of Iran with those of India, China, Greece, Japan,... and also with some religions. The items discussed in several texts of Persian literature as Ferdowsi"s Shahnameh, Nizami"s Khamseh, Attar"s Mantegh -Al- Teyr. And told that Tree between our literary symbols has a high situation.
