 abstract={Conway’s Game of Life is a popular heuristic zero-player game, devised by John Horton Conway in 1970. Its “universe” is an infinite twodimensional orthogonal grid of square cells, each of which is in one of two possible states, alive or dead. Every cell interacts with its eight neighbours, which are the cells that are directly horizontally, vertically, or diagonally adjacent. In a stepwise manner, the state of each cell in the grid preserves or alternates with respect to a given list of rules. In a previous authors’ research, for each cell its Intuitionistic Fuzzy (IF) estimation was defined as a pair consisting of the degrees lp and la, namely degrees of presence and absence of life, where lp + la ≤ 1. The article proposes intuitionistic fuzzy approaches to modifying of the Game of Life cells’ states. These approaches are based on the IF modal and extended modal operators.},
