Real-time heuristic search algorithms are useful when the amount of time or memory resources are limited or a rapid response time is required. An example of such a problem is pathfinding in video games where numerous units may be simultaneously required to react promptly to player’s commands. Classic real-time heuristic search algorithms cannot be deployed due to their obvious state-revisitatio...

the bft approach is used to formulate the electronic states in graphene through a non-commutative space in the presence of a constant magnetic field b for the first time. in this regard, we introduce a second class of constrained system, which is not gauge symmetric but by applying bft method and extending phase space, the second class constraints  converts  to the first class constraints so th...

Background The concept of decision space holds appeal as an approach to disaggregating the elements that may influence decision-making in decentralized systems. This narrative review aims to explore the functioning of decision space and the factors that influence decision space.   Methods A narrative review of the literature was conducted with searches of online databases and academic journals ...

Reinforcement learning is based on exploration of the environment and receiving reward that indicates which actions taken by the agent are good and which ones are bad. In many applications receiving even the first reward may require long exploration, during which the agent has no information about its progress. This paper presents an approach that makes it possible to use pre-existing knowledge...

Now days, computer technology mostly focusing on storage space and speed With the rapid growing of important data and increased number of applications, devising new approach for efficient compression and encryption methods are playing a vital role in performance. In this work, burrows wheeler transformation is introduced for pre processing of the input data and made several performance analysis...

We view match as an operator that takes two graph-like structures (e.g., XML schemas) and produces a mapping between the nodes of these graphs that correspond semantically to each other. Semantic schema matching is based on the two ideas: (i) we discover mappings by computing semantic relations (e.g., equivalence, more general); (ii) we determine semantic relations by analyzing the meaning (con...

In this paper, we prove that every Pre A∗-algebra A with 1 is isomorphic to the Pre A∗-algebra of all global sections of a sheaf of indecomposable Pre A∗-algebra over Boolean space and that sheaf of indecomposable Pre A∗-algebra with 1 over Boolean space is isomorphic to the sheaf obtained from the Pre A∗-algebra of all sections of the sheaf.

Assessment Of Aesthetic Quality Of Urban Green Space From The User’s Perspective In Sustainable Urban Regeneration Approach Of Historic Core Of Tehran: (The Case Of Compare Between Bab Homayon Street And Imam Khomeini Street)

the character of cosmopolitanism in e-commerce disputes is much more complicated than in normal international transactions. internet environment has created challenges and changes about the governing law of contracts in this space. this cyber space has technical and legal differences in compared with physical environment. in this paper, we intend to answer this question that in dispute arising ...
