Tokugawa clan

The Tokugawa clan was a powerful daimyō family of Japan. They nominally descended from Emperor Seiwa and were a branch of the Minamoto clan by the Nitta clan; the early history of this clan remains a mystery. Members of the clan ruled Japan as shōguns from 1603 to 1867. Minamoto no Yoshishige, grandson of Minamoto no Yoshiie, was the first to take the name of Nitta, he sided with his cousin Minamoto no Yoritomo against the Taira clan and accompanied him to Kamakura. Nitta Yoshisue, 4th son of Yoshishige, took the name of that place, their provincial history book did not mention Nitta clan. The nominal originator of the Matsudaira clan was Matsudaira Chikauji, a poor Buddhist monk, he descended from Nitta Yoshisue in the 8th generation and witnessed the ruin of the Nitta in their war against the Ashikaga. He was adopted by his wife's family, their provincial history book claimed. Because this place is said to have been reclaimed by Nobumori Ariwara, one theory holds that Matsudaira clan was related to Ariwara no Narihira.

Matsudaira Nobumitsu, son of Chikauji, was in charge of Okazaki Castle, strengthened the authority of his family in the Mikawa province. Nobumitsu's great-great-grandson Matsudaira Kiyoyasu was assassinated. In 1567, Tokugawa Ieyasu - known as Matsudaira Motonobu - grandson of Kiyoyasu, was recognized by Emperor Ōgimachi as a descendant of Seiwa Genji; the clan rose to power at the end of the Sengoku period, to the end of the Edo period they ruled Japan as shōguns. There were fifteen Tokugawa shōguns, their dominance was so strong that some history books use the term "Tokugawa era" instead of "Edo period". Their principal family shrine is the Tōshō-gū in Nikkō, principal temple is at Kan'ei-ji in Tokyo. Heirlooms of the clan are administered by the Tokugawa Memorial Foundation. After the death of Ieyasu, in 1636, the heads of the gosanke bore the Tokugawa surname, so did the three additional branches, known as the gosankyō: the Tayasu and Shimizu family, after the ascension of Tokugawa Yoshimune.

Once a shōgun died without a living heir, both the heads of gosanke and gosankyō had priority to succeed his position. Many daimyōs descended from cadet branches of the clan, remained the surname Matsudaira. Members of the Tokugawa clan intermarried with the Imperial family. On November 9, 1867, Tokugawa Yoshinobu, the 15th and the last shōgun of Tokugawa, tendered his resignation to Emperor Meiji and formally stepped down ten days returning governing power to the Emperor, marking the end of the ruling power of the Tokugawa shogunate. By the next year, Tokugawa Iesato was chosen as the heir to Yoshinobu as the head of Tokugawa clan; the 1946 Constitution of Japan abolished the kazoku and the noble titles, making Iesato's son, Iemasa Tokugawa, no longer a prince. Iemasa had a son Iehide, who died young, so he was succeeded by one of his grandsons, Tsunenari. Tsunenari is the second son of Toyoko and Ichirō Matsudaira, he is a patrilineal descendant of Tokugawa Yorifusa, the youngest son of Tokugawa Ieyasu.

The Tokugawa's clan crest, known in Japanese as a "mon", the "triple hollyhock", has been a recognized icon in Japan, symbolizing in equal parts the Tokugawa clan and the last shogunate. The crest derives from the Kamo clan, which legendarily descended from Yatagarasu. Matsudaira village was located in Aichi Prefecture. Although Emperor Go-Yōzei offered a new crest, Ieyasu continued to use the crest, not related to Minamoto clan. In jidaigeki, the crest is shown to locate the story in the Edo period, and in works set in during the Meiji Restoration movement, the crest is used to show the bearer's allegiance to the shogunate—as opposed to the royalists, whose cause is symbolized by the Imperial throne's chrysanthemum crest. Compare with the red and white rose iconography of English Wars of the Roses, as imagined by Walter Scott earlier in the 19th century, in Anne of Geierstein.

Berth allocation problem

The berth allocation problem is a NP-complete problem in operations research, regarding the allocation of berth space for vessels in container terminals. Vessels arrive over time and the terminal operator needs to assign them to berths to be served as soon as possible. Different factors affect the time assignment of each vessel. Among models found in the literature, there are four most observed cases: discrete vs. continuous berthing space, static vs. dynamic vessel arrivals, static vs. dynamic vessel handling times, variable vessel arrivals. In the discrete problem, the quay is viewed as a finite set of berths. In the continuous problem, vessels can berth anywhere along the quay and the majority of research deals with the former case. In the static arrival problem all vessels are at the port whereas in the dynamic only a portion of the vessels to be scheduled are present; the majority of the published research in berth scheduling considers the latter case. In the static handling time problem, vessel handling times are considered as input, whereas in the dynamic they are decision variables.

In the last case, the vessel arrival times are considered as variables and are optimized. Technical restrictions such as berthing draft and inter-vessel and end-berth clearance distance are further assumptions that have been adopted in some of the studies dealing with the berth allocation problem, bringing the problem formulation closer to real world conditions. Introducing technical restrictions to existing berth allocation models is rather straightforward and it may increase the complexity of the problem but simplify the use of metaheuristics; some of the most notable objectives addressed in the literature are: Minimization of vessel total service times, Minimization of early and delayed departures, Optimization of vessel arrival times, Optimization of emissions and fuel consumption. Problems have been formulated as multi-objective as well as single and bi-level. List of NP-complete problems Quay crane scheduling Container terminals Golias, Mihalis M..
