Or several trees can be constructed parallelly to reduce the expected number of tests till classification. Decision tree learning Decision tree learning or induction of decision trees is one of the predictive modelling approaches used in statistics, data mining and machine learning. It uses a decision tree (as a predictive model) to go from observations about an item (represented in the branches) to conclusions about the item's target value (represented in the leaves).

10670220	Libertatia Libertatia Libertatia (also known as Libertalia) was a purported pirate colony founded in the late 17th century in Madagascar under the leadership of Captain James Misson (last name occasionally spelled Mission", first name occasionally "Olivier"). Background. Libertalia was a legendary free colony founded by pirates led by Captain Misson, although most historians have expressed doubts over its existence outside of literature. Libertalia got its name from the Latin word "liberi" which means "free". Misson's idea was to have his society be one in which people of all colours, creeds, and beliefs were to be free of any scrutiny. He  wanted to give the people of Libertalia their own demonym, not one of a past country of origin. Historian and activist Marcus Rediker describes the pirates as follows: The pirates were against the authoritarian institutions of their day, including monarchies, slavery, institutional religion, and the abuses associated with wealth. Like some historically documented pirates, they practiced direct democracy, where the people as a whole held the authority to make laws and rules, and also used systems of councils composed of delegates who were supposed to think of themselves as "comrades" of the general population, not rulers. They created a new  language for their colony and operated a socialist economy. The pirate utopia's motto was "for God and liberty," and its flag was white, in contrast to a Jolly Roger. Captain James Misson. According to the account in the "General History of the Pyrates", Misson was French, born in Provence, and it was while he was in Rome on leave from the French warship "Victoire" that he lost his faith, disgusted by the decadence of the Papal Court. In Rome he ran into Caraccioli – a "lewd Priest" who over the course of long voyages with little to do but talk , gradually converted Misson and a sizeable portion of the rest of the crew to his way of thinking: Embarking on a career of piracy, the 200 strong crew of the "Victoire" called upon Misson to be their captain. They shared the wealth of the ship, deciding "all should be in common." Location. The consensus of modern scholarship is that Libertalia (or Libertatia) was not a real place, but a work of fiction. Journalist Kevin Rushby toured the area seeking descendants of pirate inhabitants without success, noting “others have tried and failed many times”. There were pirate settlements on and around  Madagascar, on which Libertalia may have been based: Abraham Samuel at Port Dauphin, Adam Baldridge at Ile Ste.-Marie, and James Plaintain at Ranter Bay were all ex-pirates who founded trading posts and towns. These locations appear frequently in official accounts and letters from the period, while Libertalia appears only in Johnson's "General History, Volume 2". Johnson writes about the overall set up of Libertalia. The settlement was proposed to have an elevated fort on each side of the harbor with 40 guns in each fort, from the Portuguese. Below the fort, under the protection of the forts, was  where the living quarters along with the rest of the town was located. Libertalia was located roughly 13 miles east-south-east of the nearest town. Criticism. Johnson's “Libertalia” has been treated as completely fictional, as apocryphal, or as a utopian commentary. The inclusion of fictional accounts such as Misson's in "A General History" has caused some modern scholars to discount the entire work as a reliable source, though other portions of it have been at least partially corroborated by various sources.
