آموزش پیاده سازی گرافیکی هشت وزیر با C#
» :: آموزش پیاده سازی گرافیکی هشت وزیر حرف C#
هدف از نوشتن این مقاله آشنا اجرا کردن خواننده با الگوریتم هشت وزیر به سمت صورت گرافیکی می باشد. در این لعب ما باید هشت دستور را بگونه ای در صحه شطرنج بچینیم که هیچ یک از وزیرها، 7 دستور دیگر را اسم نکند. در این مقاله، تمام 2 نوع پیاده سازی بازگشتی و غیر بازگشتی نوشته شده است.
پس از خواندن این مقاله از دانشجویان انتظار می جدول که بتوانند الگوریتم هشت دستور را تجزیه کرده و مطابق حرف نیاز خود در محیط های مختلف طراحی و پیاده سازی کنند.
A conceptual framework of agricultural land use planning with BMP for integrated watershed management
» :: A conceptual framework of agricultural land use planning with BMP for integrated watershed management
a b s t r a c t
Land use planning is an important element of the integrated watershed management approach. It not
only influences the environmental processes such as soil and stream bed erosion, sediment and nutrient
concentrations in streams, quality of surface and ground waters in a watershed, but also affects social and
economic development in that region. Although its importance in achieving sustainable development
has long been recognized, a land use planning methodology based on a systems approach involving
realistic computational modeling and meta-heuristic optimization is still lacking in the current practice
of integrated watershed management. The present study proposes a new approach which attempts to
combine computational modeling of upland watershed processes, fluvial processes and modern heuristic
optimization techniques to address the water-land use interrelationship in its full complexity. The best
land use allocation is decided by a multi-objective function that minimizes sediment yields and nutrient
concentrations as well as the total operation/implementation cost, while the water quality and the
production benefits from agricultural exploitation are maximized. The proposed optimization strategy
considers also the preferences of land owners. The runoff model AnnAGNPS (developed by USDA), and
the channel network model CCHE1D (developed by NCCHE), are linked together to simulate sediment/
pollutant transport process at watershed scale based on any assigned land use combination. The greedy
randomized adaptive Tabu search heuristic is used to flip the land use options for finding an optimum
combination of land use allocations. The approach is demonstrated by applying it to a demonstrative case
study involving USDA Goodwin Creek experimental watershed located in northern Mississippi. The
results show the improvement of the tradeoff between benefits and costs for the watershed, after
implementing the proposed optimal land use planning.

پروژه ی دانشجویی آموزش ساختمان داده ها در مقطع کارشناسی رشته ی مهندسی کامپیوتر
شرح پروژه:
برای آراسته کردن اعداد به صورت صعودی یا نزولی، راه های متفاوتی وجود دارد. ده مورد از آیین های مرتب سازی اعداد را تعیین کنید و تابع آن ها را بنویسید.
آن‌گاه پنج آرایه از اعداد s را انتخاب کنید که طول آن ها به ترتیب 10، 100، 1000، 10000، و 100000 باشد.
آن‌گاه در یک جدول، مدت زمانی که درازا می کشد تا این آرایه ها مرتب شوند را در هر روش محاسبه کنید.
نکات مورد توجه در برنامه:
لسان برنامه نویسی: سی پلاس پلاس
تنها زمان: میلی ثانیه
صفت محاسبه ی دوران باید نوشته شود.
صفت پر اجرا کردن آرایه ها با اعداد تصادفی باید نوشته شود.
تابع مرتب سازی صعودی به روش های پایین باید نوشته شود:
bubble sort (normal)
bubble sort (with macro)
bubble sort (with functioan)
insertion sort
binary insertion sort
selection sort
exchange sort
heap sort
quick sort (first function)
quick sort (second function)
