program on his computer."This creates an opportunity for virus makers," said Mikko Hypponen, head of anti-virus research at F-Secure Finland. These Backdoor programs may be exploited by arbitrary malware. When this happens, it will become more difficult for companies like ours to differentiate between legitimate software and malware."Facts have proved that in addition to 64-bit Windows operating systems, v

One layer stripped your mind: Decoding the ZeuS online banking trojan in "Deep disguise" At the very beginning, I receive a block of diaoyumail with A. Doc attachment. We took off the camouflage coat of the ZeuS Trojan step by step using the usual tool Notepad ++, and conducted a very in-depth static analysis. The disguise of this trojan uses a number of key technologies, such as information hiding and encryption and decryption. 0 × 01 found tricky At the very beginning, I encountered a very spe

Step One: Install malicious software that steals credit card credentials The attackers first stole the voucher from Target air conditioner supplier Fazio Mechanical Services. According to Kreson security, which first broke the compliance story, the attackers first carried out an infection of the supplier's fishing activities via email and

state sets, and its coherent state changes to achieve interaction with the player. NPCs and players together form the role group in the game.On the other hand, one of the core elements of AI technology in the game is the intelligent pathfinding of the characters in the game, the characters can avoid obstacles like people to choose a reasonable path from the starting point to reach the destination, or guide the player to the designated location in the virtual scene. The search algorithm in game

. Best-first-Search: BSF selects the node closest to the target for each expansion. Dijkstra selects the node closest to the data starting point each time. The difference is that the distance from the start point is always known, and the distance from the end point can only be estimated. Therefore, BSF provides a heuristic function H. Common heuristic functions H include: Calculate the absolut

the scene according to the graph. In the NPC Ondie () event, instead of destroy the object directly, it closes the NPC's breath, then opens a reborn timer and finally sets the object to Invisable. This design, can realize the NPC asynchronous refresh, save the server resources, but also let the players feel more real.The application of heuristic search (heuristic searching) in NPC intelligence is supplemen

from experience The program must do this. Connection-based and neural network processing for AI is dedicated to this. Also This includes learning the rules expressed in logic. [Mit97] is an undergraduate course on machine learning. Program You can only learn the facts and actions that can be expressed in their forms, but unfortunately It is based on a very limited ability to represent information. Planning The planning procedure is expressed in regard to the world (especially the facts about t

non-trivial: I saw a non-trivial word in a paper today. I searched it online, it means that the interpretation of this equation is complex. It may not be able to be obtained within a limited period of time, or the time complexity is very high. heristically: heuristic in Chinese. heuristic method refers to a method used by people to discover problems based on empirical rules. It is characteristic that

imagined ". Artificial Intelligence started with philosophical speculation, and went through a stage without the help of Psychology (especially cognitive neuroscience). It is only through the induction and inner of the external manifestation of human thinking, and the most exciting thing about the exploration of mathematical toolsHerbert Simon(Father of decision-making theory, Nobel Prize, cross-domain cool-man) an automatic proof machine proves more than 20 theorems in Russell's mathematical p

almost equivalent to the space occupied by the data itself. When using an open addressing strategy to avoid collisions, all key-value pairs are stored in the storage space of the hash table itself, and we do not need additional definition data structures. Collision Avoidance: Let's consider the insert operation, given a key, if the key corresponding to the hash slot has been occupied, we have to find an empty location to store the corresponding key value and its data. The general scenario is to

A * search algorithm, also known as the astar algorithm, is one of the heuristic search algorithms. It is a path with multiple nodes on the graphic plane to find the lowest cost. It is often used in the mobile computing of the NPC in the game or the mobile computing of the BOT in the online game. Like Dijkstra, this algorithm can find a shortest path and perform heuristic search like BFs. A * the most impor

Part 1: A * algorithm OverviewA * algorithm is a typical Heuristic Search Algorithm in artificial intelligence. I. What is a heuristic search algorithm: Before you start, you need to search for the status space. Status space search. If it is based on a professional point, the problem solving process is represented by the process of searching for this path from the initial state to the target State. In layma

fragmentation hinders the application of complex patterns because it produces many small trees, and too aggressive replication produces inefficient code because many operations in the final code do not have to be repeated unnecessarily. So both of these practices lead to suboptimal code. In addition, the intermediate result of a split Dag must be temporarily saved, which is cumbersome for memory-register promiscuous architectures. Finally, the question was investigated by Araujo and other "17".

. Testers can select different combinations of inputs from the causality diagram as test cases. When generating test cases, the combination explosion of the number of test cases can be effectively solved by using a specific heuristic method."Cause" refers to any input conditions that can affect software output in software requirements. "Result" refers to the response of the software to the combination of certain input conditions. The "results" here ca

) Merge two sets. Our most commonly used data structures are the forest implementations that are set and checked. In other words, in the forest, each tree represents a collection, and a root is used to identify a collection. It is not important that the morphology of the tree is in and of itself, but what is important is that there are elements in each tree. 1. Merging operations In order to get the two sets S1 and S2 together, only the father of the root of S1 is set to the root of the S2 (or t

In fact, the overall accuracy of anti-malware scans is surprisingly poor, especially for 0day vulnerabilities. After all, cracker (refers to malicious cracked or destroyed a program, system and network security, hacker and cracker have the essential difference, I think not translation more accurate expression) can arbitrarily change their tactics, and sometimes change a few bytes, you can avoid antivirus software scanning. In order to solve this prob
