  2. Peek (data type operation) - Wikipedia

    en.wikipedia.org/wiki/Peek_(data_type_operation)

    In computer science, peek is an operation on certain abstract data types, specifically sequential collections such as stacks and queues, which returns the value of the top ("front") of the collection without removing the element from the collection. It thus returns the same value as operations such as "pop" or "dequeue", but does not modify the ...

  3. Maximum subarray problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_subarray_problem

    Maximum subarray problems arise in many fields, such as genomic sequence analysis and computer vision.. Genomic sequence analysis employs maximum subarray algorithms to identify important biological segments of protein sequences that have unusual properties, by assigning scores to points within the sequence that are positive when a motif to be recognized is present, and negative when it is not ...

  5. Topographic isolation - Wikipedia

    en.wikipedia.org/wiki/Topographic_isolation

    The nearest peak to Germany's highest mountain, the 2,962-metre (9,718 ft) high Zugspitze, that has a 2,962-metre (9,718 ft) contour is the 2,988-metre (9,803 ft) Zwölferkogel in Austria's Stubai Alps. The distance between the Zugspitze and this contour is 25.8 kilometres (16 mi); the Zugspitze is thus the highest peak for a radius of 25.8 ...

  6. Iron peak - Wikipedia

    en.wikipedia.org/wiki/Iron_peak

    The iron peak is a local maximum in the vicinity of Fe (Cr, Mn, Fe, Co and Ni) on the graph of the abundances of the chemical elements. For elements lighter than iron on the periodic table, nuclear fusion releases energy. For iron, and for all of the heavier elements, nuclear fusion consumes energy.

  7. Mountain car problem - Wikipedia

    en.wikipedia.org/wiki/Mountain_car_problem

    The mountain car problem, although fairly simple, is commonly applied because it requires a reinforcement learning agent to learn on two continuous variables: position and velocity. For any given state (position and velocity) of the car, the agent is given the possibility of driving left, driving right, or not using the engine at all.

  8. Ultra-prominent peak - Wikipedia

    en.wikipedia.org/wiki/Ultra-prominent_peak

    An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of 1,500 metres (4,900 ft) or more; it is also called a P1500. [1] The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak.

  9. Peak ring - Wikipedia

    en.wikipedia.org/wiki/Peak_ring

    The Apollo basin is a peak ring crater. A peak ring crater is a type of complex crater, which is different from a multi-ringed basin or central-peak crater. A central peak is not seen; instead, a roughly circular ring or plateau, possibly discontinuous, surrounds the crater's center, with the crater rim still farther out from the center.
