CHE SIGNIFICA RANDOM WALK IN INGLESE
Passeggiata casuale
Una passeggiata casuale è una formalizzazione matematica di un percorso che consiste in una successione di passi casuali. Ad esempio, il percorso tracciato da una molecola mentre si muove in un liquido o un gas, il percorso di ricerca di un animale foraggiante, il prezzo di un titolo fluttuante e lo stato finanziario di un giocatore possono essere tutti modellati come passeggiate casuali, anche se Potrebbe non essere veramente casuale nella realtà. Il termine cammino casuale è stato introdotto da Karl Pearson nel 1905. Passeggiate casuali sono state utilizzate in molti campi: ecologia, economia, psicologia, informatica, fisica, chimica e biologia. Le passeggiate casuali spiegano i comportamenti osservati di molti processi in questi campi e servono quindi come modello fondamentale per l'attività stocastica registrata. Sono interessanti diversi tipi di passeggiate casuali. Spesso, passeggiate casuali si presume siano catene di Markov o processi di Markov, ma anche altre passeggiate più complesse sono di interesse. Alcune passeggiate casuali sono sui grafici, altri sulla linea, nel piano, nelle dimensioni superiori o addirittura su superfici curve, mentre alcune passeggiate casuali sono sui gruppi. Le passeggiate casuali variano anche per quanto riguarda il parametro del tempo.
definizione di random walk nel dizionario inglese
La definizione di passeggiata casuale nel dizionario è un modello matematico utilizzato per descrivere processi fisici, come la diffusione, in cui una particella si muove in passi lineari di lunghezza costante ma direzione casuale. L'altra definizione di camminata casuale è un percorso costituito da fasi successive e connesse in cui ogni passo è scelto da un meccanismo casuale non influenzato da alcun passaggio precedente.
