Contextual Race Generation

Mario Kart World patent US20260042016/JP2026028336:

After a race is concluded, based on various factors such direction and distance (imgs 1-2), new races of routes and courses are contextually generated (img 3) and presented to the players for voting (img 4).

Excerpt from patent US 20260042016: Specifically, first, the number of candidates of the first type to be generated in the first process is determined by a random lottery. For example, the number of candidates of the first type is determined as “3” by the random lottery. In this case, if there are three or more base areas joined to the origin area by inter-base routes R, three base areas are randomly extracted from among the three or more base areas. Here, a base area used in the most recent predetermined number of races is eliminated from base areas as extraction targets.
Excerpt from patent US 20260042016: More specifically, regarding each base area set on the field, an evaluation value f(x) is calculated using the following formula 1. Notebook[List[Cell[BoxData[FormBox[GridBox[List[List[StyleBox[RowBox[List[RowBox[List["f", "(", "x", ")"]], "=", RowBox[List[RowBox[List[RowBox[List["{", RowBox[List[FractionBox[RowBox[List["x", "\[CenterDot]", RowBox[List["(", RowBox[List[SubscriptBox[RowBox[List["\[Sum]", " "]], "n"], SubscriptBox["u", "n"]]], ")"]]]], "2"], "+", "1"]], "}"]], "A"]], "+", RowBox[List["L", FractionBox[RowBox[List["M", SuperscriptBox["e", FractionBox["x", "M"]]]], RowBox[List["\[LeftDoubleBracketingBar]", "x", "\[RightDoubleBracketingBar]"]]]]]]]]], Rule[SpanSymmetric, False]], RowBox[List["[", RowBox[List["Math", ".", " ", "1"]], "]"]]]], Rule[GridBoxAlignment, List[Rule["ColumnsIndexed", List[Rule[1, Center], Rule[2, Right]]], Rule["ItemsIndexed", List[Rule[List[1, 2], Top]]]]], Rule[GridBoxItemSize, List[Rule["ColumnsIndexed", List[Rule[1, Fit]]]]], Rule[GridBoxItemStyle, List[Rule["ItemsIndexed", List[Rule[List[1, 1], List[Rule[TextAlignment, Center]]], Rule[List[1, 2], List["EquationLabel"]]]]]], Rule[GridBoxSpacings, List[Rule["Columns", List[List[0.2]]]]]], TraditionalForm]], "Input"]]] Here, “x” is a vector from the origin area to the base area as the calculation target of the evaluation value. “un” is a vector from the origin area to an already extracted base area (candidate). “n” is the number of already extracted base areas. A, L, and M are constants, and e is the base of a natural logarithm.
