With the rapid development of network technology, all kinds of new media continue to emerge, and the "full-scale" zero-day difference of new media communication breaks through the scale of time and space. The era has come full circle. Today, "post-90s" counselors have gradually become the backbone of college counselors. At the same time, "post-00s" college students have gradually entered the campus and become the main force on campus. Counseling is a traditional profession. In the new era and new starting point, when the "post-00s" college freshmen begin to step into college campuses, how should the new counselors of the "post-90s" get along with them? The author believes that it is necessary to inherit the fine traditions, combine the characteristics of the times and the characteristics of new students, develop and innovate, pay close attention to the style of study, deepen the students, cultivate the backbone, work together at home and school, and study at all times so as to provide the source of living water and motivation for the growth of students. In the first month of college freshmen entering the school, they are still in the stage of exploration and adaptation, their study and living habits are not fixed, their learning methods have changed from supervised passive learning to conscious and active learning, and their lifestyles are also dominated by self-planning and self-management. After the "fresh period," many freshmen show negative characteristics, such as weak self-discipline, laziness, and slack, and are full of confusion and contradictions. Guilt for not making progress. The decision at this stage is particularly important for freshmen to successfully complete their studies and discover their own value. Therefore, in view of the situation that freshmen cannot adapt to the new environment as soon as possible after being separated from the familiar environment, we should guide students to establish a positive learning and life attitude in the university from multiple angles, all-round and multiple ways, and integrate into the new life as soon as possible. This paper introduces the research status of ant colony algorithm and the existing path planning algorithms and space planning methods. Combined with the relevant knowledge of graph theory, the grid method is used to establish a space model. [ABSTRACT FROM AUTHOR]
