As the mobile internet playing an increasingly important role in people.s daily life, the copyright issue of Android applications attaches more and more attentions. Because Android applications are vulnerable to reverse engineering, there are many criminals illegally modify and re-sign the official android for their own interests, which has seriously damaged the user.s rights and disturbed the order of the mobile internet. In this paper, a novel detects method of Android applications similarity based on the authors. programming style is described. In the proposed method, we firstly extract a series of basic features that can represent the programming style of author. Considering that the features selected manually are highly subjective, we tried ICA, PCA and LDA to optimize the features. Ultimately, an Extreme Learning Machine (ELM) model is trained with sequences of feature vectors. the results of experiments demonstrate that our proposed method has better performance than string comparison and grammar tree analysis when fighting against variable substitution, insert independent statement and data stream confusion.

A number of educational games have been created to help students programming. Many of these games focus on problem solving and the actual act of writing programs, while very few focus on programming comprehension. We introduce a serious game called Robot ON! aimed at players who have never programmed before. Unlike other serious programming games, Robot ON! focuses on comprehension rather than problem-solving challenges;players do not actually write any programs, but are instead given the task of demonstrating their knowledge and understanding of a program's behavior. Robot ON! includes tools that allow players to demonstrate understanding of variable values, data types, program statements, and control flow. We include an evaluation plan to assess Robot ON!'s playability, enjoyment, and benefits to program comprehension.

this system's approach to the attribute selection task was to use a genetic programming algorithm to search for a solution to the task. the evolved programs for the furniture and people domain exhibit quite naive behavior, and the DICE and MASI scores on the training sets reflect the poor humanlikeness of the programs.

In this paper, unified power flow controller is used to improve maximum total transfer capability per fuel cost. the transfer capability is the capability of power transferring in electrical power system. the fuel cost is determined by using economic dispatch concept. this ratio of total transfer capability per fuel cost is named benefit. Evolutionary programming is used to determine optimal allocations of unified power flow controller. the optimal allocations are optimal parameter settings and optimal location. the IEEE 30-bus system is used to demonstrate as test system. Test results show that evolutionary programming can determine the optimal allocation of unified power flow controller. In addition, the installation of unified power flow controller can improve the best maximization of total transfer capability per fuel cost than without the installation of unified power flow controller.

this paper proposes a constructive logic in which a concurrent System can be defined as a proof of a specification. the logic is defined by adding stream types and several rules for them to a simple constructive logic based on intuitionism. the unique feature of the obtained system is in the (MPST) rule, which is a kind of structural induction on streams. the (MPST) rule is based on the idea of Brouwer's theory of choice sequences in intuitionism and it allows to define a concurrent process, which is actually a Purge's mapstream function, as a proof of a specification with a good intuition on computation. Several techniques for defining stream-based concurrent programs are also presented through various examples.
