Compressibility regards the reduction the length of the input, or of some other parameter, preserving the solution. Any 3-SAT instance on N variables can be represented by O(N) bits. [4] proved that the instance length in general cannot be compressed to O(N3−!) bits under the assumption NP !⊆ coNP/poly, which implies that the polynomial hierarchy collapses. This note initiates and puts forward ...
چکیده قاجارها و حکومت پهلوی اول علی بازوند موضوع انقراض سلسله قاجار و انتقال حکومت به پهلوی از رخدادهای مهم تاریخ معاصر ایران است . که در این پژوهش به چگونگی نقش و عملکرد دیوان سالاران ، شاهزادگان و رجال خاندان قاجاری در این انتقال قدرت و نحوه ی برخورد رضاشاه با قاجارها دردوران سلطنت به آن پرداخته شده است . برای پاسخ به این مسأله ، بررسی های انجام گرفته بیانگر آن است که مخالفت افراد قاج...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
We present an approach applicable to certain instances of the generalized Baues problem of Billera, Kapranov, and Sturmfels. This approach involves two applications of Alexander/Spanier-Whitehead duality. We use this to show that the generalized Baues problem has a positive answer for the surjective map of cyclic polytopes C (n; d) ! C (n; 2) if n < 2d + 2 and d 9.
the issue of renunciation (i‘rāḍ) is not discussed separately among the jurists and is only implicitly referred to in some instances. it is also neglected in statutes; and most of legal experts, following the laws and like jurists, have not talked in detail on this issue. discussing the nature of renunciation, we seek here to elucidate a rather complicated issue, namely, the impact of renunciat...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
In our previous research work, we have studied the detection and the use of symmetries to improve the eeciency of satissability algorithms. We have believed that the most hard SAT problems present strucural properties such as symmetries. However, recently several authors have exhibited a threshold phenomena on randomly generated K-SAT instances. It is shown that hard instances can be generated ...
