This paper proposes a new approach to the evaluation of investment attractiveness of innovative projects in the linguistic uncertainty caused by the nature of qualitative criteria to be applied. The authors propose an economic and mathematical model that supports decision-making about the level of investment attractiveness of the project that is based on the use of the mathematical apparatus of the theory of fuzzy algebra and implemented with specialized package Fuzzy Logic Toolbox in the system MATLAB. The advantage of using this model is the ability to formally describe the knowledge of experts and professionals in selecting strategic guiding economic and production structures, in addition to evaluating the economic benefits of the project semi-structured assessment of social utility and environmental safety.безопасности.

The problem is to construct the differences of LaTeX documents. Each document is represented as a parse tree whose nodes are called tokens. All of the text is splitted into fragments whose boundaries correspond to tokens. The map of the text fragments and the corresponding map of characters is constructed. Tokens, that chars are all deleted, or all inserted, or all not changed, are selected. The map for the trees formed with other tokens is built using Zhang-Shasha algorithm.
