Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: The calculus of variations inogona kutaurwa kuti inotanga neNewton's minimal resistance problem muna 1687, ichiteverwa ne brachistochrone curve problem yakamutswa naJohann Bernoulli (1696). Yakakurumidza kubata Jakob Bernoulli naMarchis de l'Hôpital, asi Leonhard Euler akatanga kurondedzera nhau yacho, kutanga muna 1733. Lagrange akafurirwa nebasa raEuler kuti abatsire zvikuru dzidziso yacho. Pashure pokunge Euler aona basa ra1755 raLagrange aiva nemakore 19, Euler akasiya nzira yake yokuongorora zvinhu achitsigira nzira yaLagrange yokuongorora zvinhu chete uye akatumidza nyaya yacho kuti calculus of variations muhurukuro yake ya1756 Elementa Calculi Variationum. Legendre (1786) akaronga nzira, isina kunyatsogutsa, yokusiyanisa pakati pezvakakura nezviduku. Isaac Newton naGottfried Leibniz vakapawo ngwariro yapakuvamba panhau yacho. Kune uku kusarura Vincenzo Brunacci (1810), Carl Friedrich Gauss (1829), Siméon Poisson (1831), Mikhail Ostrogradsky (1834), naCarl Jacobi (1837) vave vari pakati pevabatsiri. Basa guru rinokosha ndiro raSarrus (1842) iro rakapfupikiswa ndokuvandudzwa naCauchy (1844). Mamwe manyoro anokosha uye ndangariro zvakanyorwa naStrauch (1849), Jellett (1850), Otto Hesse (1857), Alfred Clebsch (1858), uye Carll (1885), asi zvichida basa rinokosha zvikurusa rezana ramakore iri nderaWeierstrass. Nzira yake yakakurumbira yedzidziso yacho inogadzira nhambo, uye kunogona kunzi ndiye akanga ari wokutanga kuiisa panheyo yakasimba uye isingarambiki. Dambudziko rechi20 nerechi23 raHilbert rakabudiswa muna 1900 rakakurudzira kumwe kufambira mberi. Muzana ramakore rechi20 David Hilbert, Emmy Noether, Leonida Tonelli, Henri Lebesgue naJacques Hadamard pakati pevamwe vakaita mipiro inokosha. Marston Morse akashandisa calculus yokusiyana-siyana mune zvinozivikanwa zvino seMorse theory. Lev Pontryagin, Ralph Rockafellar naF. H. Clarke vakagadzira zvishandiso zvitsva zvemasvomhu zvekuverenga kwekusiyana mune yakanakisa kudzora dzidziso. Kuronga kwokuchinja kwaRichard Bellman...  Mubvunzo: Ndeipi iri zita rorondedzero iyo Alfred Clebsch akaisa pakambani yake?
